At a grocery store, the number of customers arriving per hour is shown by the function f(x) = -x^+ 2x + 2. Find the number of customers that arrived in the 6th hour.

What is the power of x?
To find the number of customers that arrived in the 6th hour, we need to evaluate the function f(x) = -x^2 + 2x + 2 when x = 6.
Step 1: Replace x with 6 in the function f(x) = -x^2 + 2x + 2.
f(6) = -(6)^2 + 2(6) + 2
Step 2: Simplify the expression.
f(6) = -36 + 12 + 2
f(6) = -36 + 14
f(6) = -22
Therefore, the number of customers that arrived in the 6th hour is -22.
