F: x 5 – 3x. (a) Find f(–1). (b) Find f –1(x).

Step-by-step explanation:

Given

Required

and

Solving for f(-1)

Substitute -1 for x in

Solving for

Let y = f(x)

Interchange the position of x and y

Make y the subject of formula (add 3y to both sides)

Subtract x from both sides

Divide through by 3

Replace y with

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
