Which function has the most x-intercepts?

1 Answer

  • g(x) looks like it has 4. In the interval from 0 to 2pi, h(x) only has 2.

    f(x) is a 3rd degree polynomial. For polynomials, the degree determines the maximum number of

    intercepts. It can't have more than 3.

    So g(x) is the winner.
