02:Posttest Functions and Graphs 1 if f(x) = x2 + 7, what is the equation for '(x)? 41(x) = + √x + 7 1-1(x) = + √x-7 11(x) = 1 Wx-7 f(x) = ± √x + 7​

b

step-by-step explanation:

the word superfluous means unnecessary

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
