Dillon Harris · Answer 1

Replace f (x) with y

switch x and y

solve for y

replace y with f⁻¹ (x)

f (x) = x-1

y=x-1

x=y-1

x+1=y

x+1=f⁻¹ (x)

f⁻¹ (x) = x+1

Finley Gibbs · Answer 2

1. substitute y for f (x) y=8x

2. switch x and y x=8y

3. solve for y y=x/8

4. plug f (x) ^-1 back in for y f (x) ^ (-1) = x/8
