Question

Lynn, Jude, and Anne were given the function f(x)= -2x^2+32, and they were asked to find f(4). Lynn's answer was 16, Jude's answer was 0, and Anne's answer was ±2. Who is correct?

Answer 1

Jude is correct

Explanation:

Our input value is given to us which is 4. Which means we would replace the x values in the function to 4 ==> f(4)= -2(4)^2 + 32 which simplifies to -2(16)+32 which then comes out as 0.
