Quadratic Functions Equations

Standard form of a quadratic equation

• y=x²

• y=ax²+bx+c

• y=mx+b

• y=x

• a = 2, b = -3, c = 9

• a = 2, b = 3, c = 0

• a = 2, b = 3, c = 9

• a = 3, b = 9, c = 2

Determine the values of a, b, and c for the quadratic equation:  4x² – 8x = 3

• a = 4, b = -8, c = 3
