11-14.
  1. For the parabola y = 2x2 − 7x + 3: Homework Help ✎

    1. Give the coordinates of the y-intercept.

    2. Give the coordinates of the two x-intercepts. Explain how you found them.

At the y-intercept, x = 0.

y-intercept: (0, 3)

At the x-intercept, y = 0.

Substitute 0 for y and factor the equation.

(2x − 1)(x − 3) = 0

Use the Zero Product Property to solve for x.

x-intercepts: (0.5, 0) and (0, 3)
