Question

Find the inflection points of f(x)=x^4+x^3-30x^2+5

Answer 1

The inflection points are defined as the points where the second derivative is equal to zero. Find the second derivative and find which values of x cause that function to equal zero.

Answer 2

Take double derivative and set it equal to zero then solve for x
x=-5/2
x=2
