Question

what is the range of this function?
{y|y > 0}
{y|y > 1}
{y|y ≥ 0}
{y|y ≥ 1}

Explanation:

Step1: Identify lowest y-value

The graph has a closed dot at $x=-7$, $y=0$, so $y$ can equal 0.

Step2: Identify upper y-behavior

The graph increases upward indefinitely, so $y$ can be all values greater than or equal to 0.

Answer:

$\{y|y \geq 0\}$
