Here are the solutions for questions 8, 9, and 10.

Question 8:

a) Copy and complete the tables of values for the relation y=2x2+5x−3y = 2x^2 + 5x - 3.

Step 1: Calculate yy values for each xx using the equation y=2x2+5x−3y = 2x^2 + 5x - 3.

  • For x=−4x = -4: y=2(−4)2+5(−4)−3=2(16)−20−3=32−20−3=9y = 2(-4)^2 + 5(-4) - 3 = 2(16) - 20 - 3 = 32 - 20 - 3 = 9.
  • For x=−3x = -3: $
