Question

What is the y-intercept of f^-1(x)?

Answer 1

Answer:

-12

Step-by-step explanation:

Take the inverse function, and modulate it:

${f}^{- 1} (x) = \frac{4}{3} x - 12$

By taking x = 0, we can see that the y-intercept is clearly -12:

$\frac{4}{3} (0) - 12 = - 12$

Therefore, the y-intercept is -12.
