Question

Для функции f (x) = - x^2+2x+13 найдите f (-2)

Answer 1

Ответ:

5

Объяснение:

$f( - 2) = - {( - 2)}^{2} + 2 \times ( - 2) + 13 = \\ = - 4 - 4 + 13 = 5$

Answer 2

To find the value of the function f(x) = -x^2 + 2x + 13 when x = -2, you simply need to substitute -2 in place of x in the expression and evaluate the result.

f(-2) = -(-2)^2 + 2(-2) + 13 = -(4) + (-4) + 13 = -4 - 4 + 13 = 5

Therefore, f(-2) = 5.
