What is the maximum number of relative extrema contained is the graph of this function?
f(x)=3x^4-x^2+4x-2

The maximum number of relative extema contained in a polynomial =degree of this polynomial - 1.

The degree of this polynomial is 4, therefore: the maximum number of relative extrema contained in the graph of this function will be:4-1=3

The maximum number of relative extrema would be 3.

Ithink the answer is d.
