Derivative Question?

Question

Consider the function y = 3x5 &ndash; 25x3 + 60x + 1. Use the first or second derivative test to test the critical points. How many relative maxima did you find? 

So I tried this question and got 2, but I wasn't sure if I did this correctly.

Answer

Using second derivative test y''=0 ,but your equation do 
Not have an exponet your. Second derivative test will be
Equal to zero therefoe your points will be(0:0)
*step 1- y'=0-0+0+1
*step 2: y''=0
*therefore x=o
N.B(I worked this using x as an alpher)
