Question

What is the range for the graph shown?A) $- 3 \leqslant y \leqslant 2$B) $- 3 \: and \: 2$C) $- 3 \leqslant y \leqslant 3$D) $- 2 \leqslant y \leqslant 3$

Answer 1

The range of a function is the interval of values that it takes on the Y-axis.

From the figure, we can see that the lowest value on the Y-axis is -2 and the greatest value is 3.

Therefore, the range of the graph shown is [-2 , 3].

It can also be written as:

$-2\leq y\leq3$
