Domain and range? ugh confusing

Maybe both Domain and range are 0 to positive infinity in the graph shown here.

BUT

This graph seems incorrect because m squared would normally be a parabola, not a straight line.

Anyway. . .

Step-by-step explanation:

Range is normally the lowest y-value to the greatest y-value. You might remember that you go up and down over a mountain range.

In this graph, the solid dot on 0 means the lowest value is 0. The arrow goes to positive infinity.

Domain is the lowest x-value to the greatest x-value. Here, the domain is also 0 to positive infinity.

answer: check all that apply, where the options?
