Determine the range of the function graphed below. [tex] - 7 \leqslant x \ \textless \ 7[/tex][tex] - 3 \leqslant y \leqslant 3[/tex]{-3,0,3}{-7,0,7}

the range of the function are the possible values that can take y, so we can see that the y is between -3 and 3 including both numbers so:
[tex]-3\le y\le3[/tex]
