Question

Evaluate the polynomial function at the given value. Find P(-5) if P(x)= 3x2 – 9x+8.

Answer 1

To evaluate the polynomial function, substitute the value into the function and simplify. In this case, P(-5) = 128.

Step-by-step explanation:

To evaluate the polynomial function at the given value, substitute the value into the function and simplify. In this case, we want to find P(-5) if P(x) = 3x^2 - 9x + 8.

Replacing x with -5, we get P(-5) = 3(-5)^2 - 9(-5) + 8.

Simplifying further, P(-5) = 3(25) + 45 + 8 = 75 + 45 + 8 = 128.
