Question

If f(x) = -2x - 14, then f'(x) =D
Enter the correct answer.

Answer 1

1/2x + 7 is the answer

Answer 2

f⁻¹(x) = 1/2x + 7

Explanation:

To find the inverse of a function, simply switch x and y and solve for y once more.

f(x) = -2x - 14

x = -2y - 14

x + 14 = -2y

(x + 14)/2 = f⁻¹(x)

1/2x + 7 = f⁻¹(x)
