Intercept Form Quadratic Equations

Which equation is the intercept form of a quadratic function?

• f(x) = mx + b

• f(x) = a(x - p)(x -q)

• f(x) = ax² + bx + c

• f(x) = a(x - h)² + k

What is a quadratic function in factored (intercept) form with x-intercepts of 5 and -2

• 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 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 intercept form of the quadratic shown?

• f(x) = -x(x - 4)

• f(x) = x(x - 4)

• f(x) = -x(x + 4)

• f(x) = x(x + 4)
