What is the range of the function graphed?

The correct answer is B) 
-3 < y ≤ 3

You can tell this by looking at the graph. The lowest that it goes is -3. You'll also note that the -3 has an open circle, which means that it isn't includes and thus needs a <.

The highest it goes it 3. You'll note that it has a closed circle, which means it is included and needs a ≤.

1.17+3.99a. you combine the terms with a to create 3.99 and the 1.17 stays because it has no like terms or a variable
