Answer 1

Answer:

2/3

Step-by-step explanation:

so the inverse takes us from the range to the domain... they tell us that  f(4) goes to 5.. so if we were to take the inverse  f$\left \[-1} \atop$(5)  it takes us back to 4... and the slope at 4 or the derivative was 2/3 so that's what we get for f$\left \ {{-1} \atop$ '(5)  :)
