Answer:
f(-1) = 5
Step-by-step explanation:
To "evaluate the function f(x) = -x^2 + 6 at x = -1, we substitute -1 for x in each instance:
f(-1) = -(-1)^2 + 6
According to order of operations rules, exponentiation must be performed before multiplication or division. '-(-1)^2' thus becomes -1, and so
f(-1) = -(-1)^2 + 6 = -1 + 6 = 5.
Thus, f(-1) = 5
