Final answer:
To find f(-5), substitute -5 into the function f(x) = -x² + 3x - 7, and simplify. The steps include squaring -5, multiplying by -1, multiplying 3 by -5, and then adding all terms together, resulting in f(-5) = -47.
Step-by-step explanation:
To find f(-5) for the function f(x) = -x² + 3x - 7, we need to substitute x with -5 in the given equation and calculate the value.
Here's the step-by-step calculation:
Therefore, f(-5) = -47.
