Question

evaluate each function for the given value.

1. $f(x) = -x^2 - 6x - 7$; find $f(-1)$

Explanation:

Step1: Substitute $x=-1$ into function

$f(-1) = -(-1)^2 - 6(-1) - 7$

Step2: Calculate exponents and products

$f(-1) = -(1) + 6 - 7$

Step3: Compute final arithmetic

$f(-1) = -1 + 6 - 7$

Answer:

$-2$
