Image Long DescriptionValues listed in x are negative 2, negative 1, 0, 1, and left bracket response right bracket. Values listed in f of x are 0, 1, and 4. Arrows pointing from the values in x to the values in f of x are as follows: negative 2 to 4, negative 1 to 1, 0 to 0, 1 to 1, and left bracket response right bracket to 4.

This map shows ordered pairs that belong to the function f(x)=x2
. What is the missing value?

(1 point)

Answer 1

2

Because f(x) = x^2 and f(x) = 4 implies x = ±2; −2 is already listed, so the other input is 2.
