Graphing Quadratics Review

Which is the standard form of a quadratic equation?

• y= ax²+bx+c

• y= mx + b

• (y-y₁)= m(x-x₁)

• y= a(x-h)²+k

Which is the vertex form of a quadratic equation?

• y= ax²+bc+c

• y= mx + b

• (y-y₁)= m(x-x₁)

• y= a(x-h)²+k

Convert to Standard Form: y = 2(x-3)²-4

• y = 2x²-12x+9

• y = 2x²-12x+14

• y = x²-6x+5

• y = 2x²-12x+18
