Question

F(x) = -10x-6, then f¹(x) =

Answer 1

- x + 6 / 10

Explanation:

^−1() means the function inverse to . More often people write ^−1(), they usually take x as the independent variable for f and y as the independent variable for ^−1, like =() and =^−1().

Answer 2

f'(x) = -10

Explanation:

derivative of -10x is 1(-10)x⁰ = -10

derivative of -6 is 0.
