Part 2.] What is the inverse of the function ?

C.]

D.]

1. I believe the answer is D, y = fifth root of (x+4) / 3

y = 3x⁵ - 4

Interchanging x and y

x = 3y⁵ - 4

solving for y in the equation; x=3y⁵-4

y = ((x+4) / 3) ^1/5

= ((x+4) / 3) ^1/5

2. inverse of the equation y = 3e^-4x+1

I think the answer is D;

Interchanging the variables x and y

x = 3e^-4y-1

Solving for y in x = 3e^-4y + 1

y = - (In (x/3) - 1) / 4

= (1-In (x/3)) / 4
