The y-intercept is g(0), which is 0. So the answer is either a or c.

An x-intercept indicates a root of the polynomial; any polynomial of degree n has exactly n roots. The maximum number of x-intercepts is when the roots are all distinct. Since this polynomial is degree 6, the maximum number of x-intercepts is 6, so the answer is a.

g%28x%29+=ax%5E6%2Bbx%5E3%2B3x
if there is no constant, the y-intercept is 0
if polynomial is function of degree 6, the maximum possible number of x-intercepts is 6

answer: a. 0 and 6
