8-119.

Sketch the graph of each polynomial function below and identify all of the zeros. Homework Help ✎

*y*=*x*^{3}+ 1*y*=*x*^{3}– 8

These are both cubic functions, shifted vertically.

Each function has one *x*-intercept, which is a zero of the function. Divide the polynomial by the associated factor to obtain a quadratic factor. Then use the Quadratic Formula to obtain the other two (complex) zeros.
