Which equation is in intercept form? (also known as factored form)

• f(x) = 3x +2

• f(x) = -3(x - 1)(x + 5)

• f(x) = x² + 2x + 3

• f(x) = -4(x - 2)² + 1

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)
