Write the equation of the quadratic function in Intercept Form using the x-intercepts and ANY point on the graph.. Remember: Intercept form is written as y = a(x-p)(x-q)

• y =(x - 1)(x - 3)

• y = -1/2(x - 1)(x + 3)

• y = 2(x + 1)(x - 3)

• y = - 1(x - 1)(x - 3)

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)
