Question

Which of the following values are in the range of the function graphed below? Check all that apply.

Answer 1

The correct answers are D. 0 and E. 1

A function $f$ from a set A to a set B is a relation that assigns to each element $x$ in the set A exactly one element in the set B. The set A is the domain (also called set of inputs) of the function and the set B contains the range (also called set of outputs). According to this statement the set of values that $y$ take is the range, so as shown in the Figure above:

First.

$y=1 \ when \ x=0$

Second.

$y=0 \ when \ x=-1 \ and \\ y=0 \ when \ x=1$
