Identify which of the following equations are quadratic function or linear function. f(x) = 2x – 5 2. y = (x + 1)(x - 6) f(x) = 6x2 – 7x – 5 y = 7x +8 y = 9x2 – 16 Complete the table veiow of the quadratic function y = x2 – 2x – 3, find the common differences and graph. 1. y = x² – 2x - 3 -2 -1 1 4 y Transform the following quadratic function ito y a(x – h)² + k. Write the 1. y = x2 – 12x + 30 2. f(x) = 2x2 + 8x - 9 → using completing the square → using the formula h and k %3D
