April 10 2024 P1/4 quadratic : Intercept Form

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 are the green dots called?

• axis of symmetry

• vertex

• parabola

• x-intercepts
