For what values of b will F(x) = logb x be an increasing function?
A. b < 0
B. b > 0
C. b < 1
D. b > 1,
Answers
logb x = n is the equivalent of asking "you should raise the base b to what number n in order to get x?": bⁿ = x
From this follows that b must be positive, otherwise the function is not defined everywhere in R: for example, take log(-2) x = 0.5 ? This means: [tex] (-2)^{1/2} [/tex] =√(-2) which is impossible in R.
Therefore, both answers A and C are not correct because they take in consideration negative values.
If we take the base between 0 and 1 excluded, we have a fraction whose denominator is bigger than the numerator. Such a fraction, elevated to increasing exponents get smaller, for example:
(1/2)² = 1/4
(1/2)³ = 1/8
(1/2)⁴ = 1/16
Therefore the function is dereasing and answer B is incorrect.
The right answer is, therefore, D) b > 1.
Final answer:
The logarithmic function F(x) = logb x is an increasing function when the base b is greater than 1, because the value of logb x increases as x increases for b > 1.(Option D)
Explanation:
The question asks for what values of b will F(x) = logb x be an increasing function. To determine this, we need to understand the behavior of logarithmic functions based on their base value (b). A logarithmic function is increasing if the base of the logarithm is greater than 1. This is because as x increases, the value of logb x increases when b>1. Conversely, if b<1 (but b>0), the function is decreasing because the power to which b must be raised to produce x decreases as x increases. We also know that the base of a logarithm cannot be negative or zero, as this would not produce a valid logarithmic function.
Therefore, the correct answer is D. b > 1, where the logarithmic function F(x) = logb x is an increasing function.

Answer:
The annual interest is,
Option d is correct
5%
The bank compounds the interest_
Option a is correct.
Annually.
The balance of the account will grow,
Option b is correct
exponentially
Step-by-step explanation:
Exponential growth function is given by:
[tex]y=(1+r)^x[/tex] .....[1]
where,
r is the annual interest in decimal
x is the number of periods.
As per the statement:
Consider the function:
[tex]y=(1.05)^{\frac{x}{12}}[/tex] where, x represents the time in months.
On comparing with [1] we have;
[tex]1+r = 1.05[/tex]
Subtract 1 from both sides we have;
r = 0.05 = 5%
The annual interest is, 5%
and
the bank compounds the interest annually.
The balance of the account will grow exponentially

In a function, there is an input and there is an output. The idea of a function is that each individual input is changed into an output.
The time it takes to cook a turkey depends on the size of the turkey.
Smaller turkeys would take less time to cook and larger turkeys would take longer to cook.
So if you start with the turkeys weight, you could determine how long it would need to cook. This is an example of a function.
The time it takes to cook a turkey is a function of the turkey’s weight. Then the correct option is C.

What are the zeros of f(x) = 4x^2 - 12x + 8 (I need a clear explanation on how to solve it)
Answers
The zero of the quadratic function is therefore x = 1. Since both factors give the same zero, we have a repeated zero and f(x) only touches the x-axis at one point, x = 1.
The zeros of the quadratic function f(x) = 4x^2 - 12x + 8 are the values of x that make f(x) = 0. In this function, we can factor by finding two numbers that multiply to give the constant term (8 times 4, the coefficient of x^2) and add to give the coefficient of x (-12). Here, those numbers are -4 and -4, so we rewrite the middle term -12x as -4x - 4x, and factor by grouping:
4x^2 - 4x - 4x + 8 = 0
4x(x - 1) - 4(x - 1) = 0
(4x - 4)(x - 1) = 0
Now we have two factors equal to zero, which gives us two equations to solve:
4x - 4 = 0 or x - 1 = 0
x = 1

solve the system of equations y=2x^2-3 y=3x-1
Answers
y = 2x^2 - 3 ---- equation 1
y = 3x - 1 ------equation 2
Then we get,
2x^2 - 3 = 3x - 1
Now, simplifying the equation, we get
2x^2 - 3x - 3 + 1 = 0
2x^2 - 3x - 2 = 0
After factoring the equation, we get
(2x+1)(x-2) = 0
So, this means
(2x+1) = 0 and (x-2) = 0
From this, we get
x = -1/2 and x = 2
Putting values of x = -1/2 in equation 2
y = 3(-1/2) - 1
y = -2.5
Now, putting value of x = 2 in equation 2
y = 3(2) -1
y = 5

Note that the given expression can also be expressed as three separate fractions summed together, i.e., (6/x-6) + (3x/x+5) - [1/(x-6)(x+5)]. Dealing with fractions in simplification, we combine them to a common denominator and rationalize the numerator and denominator. After that, simplify the resulting expression.

Answers
A(2/7:5)

The slope is 7/2.
The slope of the line y=3.5x+4 is 3.5, and the missing coordinates will be filled as a(0.28, 5) and b(10, 9)
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
The given equation of line is y=3.5x+4
When we compare this with slope intercept form y=mx+b.
slope m=3.5
We need to find the value of x when y is 5
5=3.5x+4
1=3.5x
Divide both sides by 3.5
x=0.28
So a coordinates are (0.28, 5)
Now let us find y value when x is 10
y=3.5(10)+4
y=39
So b coordinates are (0.28, 39)
Hence, the slope of the line y=3.5x+4 is 3.5, and the missing coordinates will be filled as a(0.28, 5) and b(10, 9)
