Question
Given f, of, x, equals, minus, x, squared, plus, 18f(x)=−x 2 +18, find f, of, minus, 2f(−2)
Solution
To find the value of f(-2) for the function f(x) = -x^2 + 18, you need to substitute -2 in place of x in the function.
Step 1: Substitute -2 for x in the function f(x) = -x^2 + 18 f(-2) = -(-2)^2 + 18
Step 2: Simplify the equation f(-2) = -4 + 18
Step 3: Solve the equation f(-2) = 14
So, f(-2) for the function f(x) = -x^2 + 18 is 14.
