Answer:
The answer is 28
Step-by-step explanation:
To find the answer, take the function and input the -5 for all x's.
f(x) = x^2 - 2x - 7
f(-5) = (-5)^2 - 2(-5) - 7
f(-5) = 25 + 10 - 7
f(-5) = 28
The value of f(-5) is 28 after plugging x = -5 in the polynomial f(x) = x² - 2x - 7
Polynomial is the combination of variables and constants systematically with "n" number of power in ascending or descending order.

We have a polynomial:
f(x) = x² - 2x - 7
Plug x = -5
f(-5) = (-5)² - 2(-5) - 7
f(-5) = 25 + 10 - 7
f(-5) = 28
Thus, the value of f(-5) is 28 after plugging x = -5 in the polynomial f(x) = x² - 2x - 7
