Given f(x) = -11x² + 5, what is the value of f(4)?

Answer: f(4) = -171Step-by-step explanation:       To answer this question, we will solve the function for 4. In other words, we will input 4 into the function and simplify. Don't forget the order of PEMDAS when simplifying. Given:      f(x) = -11x² + 5Input of 4:      f(4) = -11(4)² + 5Raise to the power of 2:      f(4) = -11(16) + 5Multiply:      f(4) = -176 + 5Add:      f(4) = -171
