Answer :
Final answer:
To find f(-7), substitute -7 for x in the given function and compute the result, which is 109.
Explanation:
To find f(-7), we substitute -7 for x in the function f(x). Therefore, we have:
f(-7) = 4(-7)² - 82 - 5
f(-7) = 4(49) - 82 - 5
f(-7) = 196 - 82 - 5
f(-7) = 114 - 5
f(-7) = 109
