Question

Please help with finding relative maximums and minimums

Answer 1

I have to find the relative maxima for the function f(x) = -2x^3 - 3x^2 + 11

The critical numbers are at x = 0 and x = -1

(0,11) is a relative max and (-1,10) is a relative min

However, I looked at the graph and there should not be any critical numbers.

Can someone explain to me where I went wrong?

Answer 2

Oh I see. I should've zoomed in
