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)
What is the quadratic function for the graph in intercept form?
y = (x - 2)(x - 6)
y = - (x - 2)(x - 6)
y = (x + 2)(x + 6)
y = (x + 4)(x - 4)
x2 + 16x + 64
