Consider the following graph of a quadratic function. Which of the statements are true? Select all that apply.
A. The function is decreasing over the interval x<-1
B. The range of the function is all real numbers.
C. The function is increasing over the interval x<-1
D. The domain of the function is all real numbers
E. The function has a relative minimum at (-1,5)
Answer:
Option C,D and E are correct.
Step-by-step explanation:
Clearly from the graph we could say that it is a graph of a quadratic function.so we will work on each of the following options:
A)
Clearly from the graph we could see that the graph is increasing on both the sides of -1.
Hence, option A is wrong. ( The function is decreasing over the interval x<-1).
B)
As the function is a quadratic function hence the range contains all the real numbers greater than or equal to 5 below 5 it won't take any value.
Hence option B is wrong.(The range of the function is all real numbers).
C)
clearly we could see that the function is increasing in the interval x<-1.
Hence, option C is correct.
D)
The function is defined for all of the real numbers.
Hence option D is correct. (The domain of the function is all real numbers).
E)
Clearly from the graph we could see that the function has minimum value at -1 and the graph is increasing before and after that.
Hence, option E is correct.( The function has a relative minimum at (-1,5) ).
Answer:
C,D,E

Kerrie cover a table with 8 rows of square tiles there are 7 tiles in each row what is the area the Kerrie covers in square units?
Kerrie covered a table having 8 rows of square tiles.
Each row has 7 tiles. The table will be rectangular in shape.
The number of rows will be the length of the table and the number of tiles in each row will be the width of the table.
Area of rectangle = length x width.
Area of the table = 8x7= 56 square units.
The area covered by Kerrie is [tex] 56unit ^{2} [/tex]

Write an equation of the line that is perpendicular to the line y = 2x + 8, and which passes through the point (6,-2).
Answer: y= -1/2 + 1
Step-by-step explanation: To solve this problem, first determine the slope of your line. Since perpendicular lines have slopes that are opposite reciprocals of each other,we know that the slope is -1/2. Then plug your slip (-1/2) and point (6,-2) into the equation y=mx+b to solve for b. The resulting value for b is 1.
Which statement is NOT true?
F. A set of ordered pairs that describes a function cannot have any y-value repeated.
G. A table of values describes a function if all the x-values are different.
H. A mapping is a function if each x-value is paired with exactly one y-value.
J. A graph describes a function if no point on the graph lies directly above or below another of the graph.
The function f(x) =g(x), where f(x) =2x-3 and g(x) =x^2-5
Answer:
x=2.732
Step-by-step explanation:
Given are two functions
f(x) = 2x-3 and g(x) = [tex]x^2-5[/tex]
WE have to find the approximae value when these two funcitons are equal
Since we are asked to find only positive value we can refer table and do
f(2) >g(2) but f(3)<g(3) Hence there is one solution between 2 and 3.
f(2.5)>g(2.5). So the root lies between 2.5 and 3 since change of sign takes place here

2.732 2,464 2.464
Hence answer is x =2,732

Which steps should be followed to use a scale drawing and a new scale to find the new length of a soccer field? Add the numerator of the new scale to the old length to get the new length. Subtract the new length from the old length to find the difference in lengths. Write a proportion using the new scale as the first ratio. Set the first ratio equal to the ratio of the length of the original field compared to a variable that represents the new length of the field. Solve the proportion to find the new length of the field. Write a ratio comparing the scale drawing length to the actual length of the field, and simplify.
