Question

Найдите f(-4), если f(x)=X^2-8x

Answer 1

f(x)=x²-8x

f(-4)= (-4)² - 8·(-4)= 16 +32=48

Ответ: f(-4)=48.

Answer 2

To find the value of f(-4) using the given function f(x) = x^2 - 8x, we need to substitute -4 in place of x and evaluate the expression. Let's calculate it:

f(-4) = (-4)^2 - 8(-4) = 16 + 32 = 48

Therefore, f(-4) = 48.
