If f(x)=x-2, which of the following is the inverse of f(x)

= x + 2.

Step-by-step explanation:

Given :  f(x) = x-2.

To find : inverse of F(x).

Solution : We have given that f(x) = x-2.

STEP 1: replace  "y" in for the "f(x)":

y = x -2.

STEP 2: Switch the x and y

x = y -2 .

STEP 3: Solve for y:

On adding 2 both sides and switching the sides.

y = x + 2 .

STEP 4: write in the inverse notation

y = = x + 2.

Therefore, = x + 2.

30 people weigh 160 pounds or more

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
