What does it mean when a quadratic graph intersects the x-axis at two points?

• The equation has no solution

• The equation has one solution

• The equation has two solutions

• The equation is not quadratic

If a quadratic equation is set to equal zero, what are we essentially finding?

• The vertex of the parabola

• The slope of the line

• The x-intercepts or roots

• The y-intercept

In the example where the quadratic equation is factored into (x + 7)(x + 3) = 0, what are the roots?

• x = 0 and x = 10

• x = -3 and x = -7

• x = 7 and x = -3

• x = 3 and x = 7

What is the solution when a quadratic equation with a zero constant term is factored?

• x = -17/4 or x = 0

• x = 0 or x = -17/4
