Intercept Form Quadratics

The graph below describes a ball that was kicked. Which equation best models the graph? Use the x-intercepts and ANY point on the graph.

• y = -250(x)(x - 4)

• y = -500(x)(x - 4)

• y = -500(x)(x + 4)

• y = -250(x)(x + 4)

What is a quadratic function in factored (intercept) form with x-intercepts of (5, 0) and (-2, 0), and "a" value of 1?

• f(x) = x² + 3x -10

• f(x) = (x + 5)(x - 2)

• f(x) = (x - 5)(x + 2)

• f(x) = (x + 1.5)² - 12.25

Write an equation of this graph in intercept (factored) form.

• h(x) = (x - 1)(x + 3)

• h(x) = (x + 1)(x - 3)

• h(x) = (x + 1)(x - 1)

• h(x) = (x + 3)(x - 3)
