Quadratic from a Point and X Intercepts

Now, take the factored form and write it in Standard Form (ax²+bx+c=0) by double distributing (or FOIL).

• x²+2x-15=0

• -x²+14x -48=0

• - x²+8x-15=0

• x² + 5x -16=0

Which parabola would open down?

• f(x)=x²

• f(x)=-x²+3x-6

• f(x) = x²-16

• f(x)=2x²-5x+7
