Question

Lynn, Jude, and Anne were given the function f(x)=-2x^2+32, and they were asked to find f(3).

Lynn's answer was 14, Jude's answer was 4, and Anne's answer was +4. Who is correct

Answer 1

Lynn's answer is correct

Explanation:

f(3) = -2 x 3^2 + 32

= -2 x 9 + 32

= -18 + 32

= 14

Answer 2

Lynn is correct. f(3) = 14

Explanation:

f(x)=-2x^2+32

f(3)=-2(3)^2+32

f(3)=-2(9)+32

f(3)=-(18)+32

f(3) = 14
