2.2. Write the dual formulation of the following model: Maximise 10 x + 13 y Subject to 8 x + 2 y 34 <= 3 x + 2 y <= 27 1 y X, y >= 0 0 x + <= 4

Which equation does NOT represent a linear function of x? 4 1) y =-x 4) y = 2) y = -3+ 2x 3) у %3 3x? - 2

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