Question

f (x) = 9 x + 11. Find the inverse of f(x).
A

Answer 1

Answer:

Step-by-step explanation:

Let's solve for x.

y=9x+11

Step 1: Flip the equation.

9x+11=y

Step 2: Add -11 to both sides.

9x+11+−11=y+−11

9x=y−11

Step 3: Divide both sides by 9.

9x/9

=

y−11/9

x=1/9y+−11/9

Answer:

x=1/9y+−11/9
