Question

given the polynomial function below find F(-4) f(x)=2x^ 2 -x + 9

Answer 1

Answer:

45

Step-by-step explanation:

Answer 2

The value of f(-4) in the polynomial functions f(x) = 2x² - x + 9 is 45

How to evaluate the function?

The function is given as:

f(x) = 2x² - x + 9

Substitute -4 for x

f(-4) = 2(-4)² - (-4) + 9

Evaluate the exponents

f(-4) = 2(16) - (-4) + 9

Evaluate the product

f(-4) = 32 - (-4) + 9

Evaluate the sum and the difference

f(-4) = 45

Hence, the value of f(-4) is 45
