# Calc I

I'm a little confused about this one, it seems different from the rest of our homework! Could someone give me some hints? Thank you!

Find the first and second derivative of the function. Check to see that your answers are reasonable by comparing the graphs of
f, f ', and f ''.
f(x) = e^x − x^5

1. f ' (x) = e^x - 5x^4
f '' (x) = e^x - 20x^3
