Find the zeros of the function by solving Any real zeros are the first coordinates of the x-intercepts. Use the zeros (x-intercepts) to divide the x-axis into intervals and choose a test point in each interval to determine the sign of all function values in that interval. Find This gives the y-intercept of the function.

Use the Remainder Theorem to find zeros. Substitute a potential zero into f(x) and calculate the value. If the value = 0, then x is a zero of f(x). Use synthetic division to find the other polynomial factor. Continue until the polynomial factor is quadratic (x2). Use quadratic methods (factoring, quadratic formula, square root property) at this point to find the remaining two zeros.
