Question

Consider the polynomial function p given by p(x) = 728 – 2x2 + 32 + 10. Evaluate the functionat x = -3

Answer 1

-206

Explanation:

We are given the following function:

p(x) = 7x³ - 2x² + 3x + 10

To evaluate it at x = -3, we replace x by -3. So

p(-3) = 7x³ - 2x² + 3x + 10 = 7*(-3)³ - 2*(-3)² + 3*(-3) + 10 = 7*(-27) - 2*9 - 9 + 10 = -189 - 18 + 1 = -189 - 17 = -206
