Q1 : find the inverse of the function. f(x) = 7x - 1 (5 points) q2 : find the inverse of the function. f(x) = x3 - 7 (5 points) q3 : find the inverse of the function. f(x) = 5x3 - 3 (5 points)

1. Option D is correct.

2. Option B is correct.

3. Option B is correct.

Step-by-step explanation:

Inverse function defined as the the function that undergoes the action of the other function.

A function is the inverse of f if whenever y =f(x) and

To find the inverse of the function:

Q1.

Given the function:  f(x) = 7x -1

Put y for f(x) and solve for x;

y= 7x -1

Add 1 both sides we get;

y + 1 = 7x

Divide both sides by 7 we get;

Put for x;

Interchange y =x, we have

Q 2.

Given the function:

Put y for f(x) and solve for x;

Add 7 both sides we get;

taking cube root both sides we get

Put for x;

Interchange y =x, we have

Q3 .

Given the function:

Put y for f(x) and solve for x;

Add 3 both sides we get;

Divide both sides by 5 we get;

taking cube root both sides we get

Put for x;

Interchange y =x, we have

both graphs increase on their domain

neither graph has a y-intercept
