Accepted Solution

A:
Answer:The values of y are -33 , -15 , -5 , -5 ⇒ answer CStep-by-step explanation:* We will use the substitution method to solve the problem- The quadratic equation is y = -x² + x - 3- The values of x are -5 , -3 , -1 , 2- We will substitute the values of x in the equation to find the   values of y # At x = -5∵ y = -x² + x - 3∵ x = -5∴ y = -(-5)² + (-5) - 3 = - 25 - 5 - 3 = -33∴ y = -33# At x = -3∵ y = -x² + x - 3∵ x = -3∴ y = -(-3)² + (-3) - 3 = - 9 - 3 - 3 = -15∴ y = -15# At x = -1∵ y = -x² + x - 3∵ x = -1∴ y = -(-1)² + (-1) - 3 = - 1 - 1 - 3 = -5∴ y = -5# At x = 2∵ y = -x² + x - 3∵ x = 2∴ y = -(2)² + (2) - 3 = - 4 + 2 - 3 = -5∴ y = -5* The values of y are -33 , -15 , -5 , -5 ⇒ from left to right
