50 POINTS!!! SHOW YOUR WORK AND ANSWER CORRECTLY OR ELSE A MODERATOR WILL HANDLE YOU! Let f (x) = −x^2 − 5x + 36. What is the value of f(-3)? Show your work. Best answer gets brainliest.

$f(x) = -x^2-5x+36\qquad \qquad f(-3)=? \\ \\ \\f(-3) = -(-3)^2-5(-3)+36\\ \\f(-3) = -(9)-5(-3)+36\\ \\f(-3) = -9+15+36 \\ \\ \boxed{f(-3) = 42}$
