Question
Given f, of, x, equals, minus, x, squared, minus, xf(x)=−x 2 −x, find f, of, minus, 9f(−9)
Solution
To find the value of f(-9) for the function f(x) = -x^2 - x, you need to substitute -9 in place of x in the function.
Step 1: f(x) = -x^2 - x Step 2: Substitute -9 for x: f(-9) = -(-9)^2 - (-9) Step 3: Simplify the equation: f(-9) = -81 + 9 Step 4: Solve the equation: f(-9) = -72
So, f(-9) for the function f(x) = -x^2 - x is -72.
