8-143.
  1. Sketch the graph of each polynomial function below and find all of the zeros. Homework Help ✎

    1. y = x3 + 1

    2. y = x3 − 8

The parent graph is y = x3. How is it shifted?

This 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.
