If , find: Homework Help ✎

  1. Where p(x) intersects the y-axis.

    Substitute 0 for x, and solve for .

    (0, –6)

  2. Where p(x) intersects the x-axis.

    Substitute 0 for , and solve for x.

    You can factor and use the Zero Product Property once you write your equation.

    (–6, 0) and (1, 0)

  3. If , find the intercepts of q(x) and compare the graphs of and .

    Look at parts (a) and (b) to help find the intercepts.
    What do you notice about the graphs? Are they related?

    x-intercepts: (0, 0), (–5, 0)
    y-intercept: (0, 0)
    is 6 units lower than .

  4. Find .

    Subtract from . You should notice a relationship between your answers for parts (c) and (d).
