Given f(x)=-x^(2), find f(-4) Answer:

Given Function Substitution: We are given the function f(x) = -x^(2). To find f(-4), we need to substitute x with -4 in the function. Calculation: f(-4) = -(-4)^(2)Calculate Square: Now we calculate the square of -4. Calculation: (-4)^(2) = 16Multiply by -1: Next, we multiply the result by -1 as per the function definition. Calculation: f(-4) = -(16) = -16
