Calculating a Function Value

The image shows a function definition and a request to evaluate the function at a particular point: f(x) = x^2 - x; f(-4) To solve this, we simply substitute x with -4 in the function's equation: f(-4) = (-4)^2 - (-4) f(-4) = 16 + 4 f(-4) = 20 Therefore, f(-4) is equal to 20.
