Question

What is the range of this equation

This is college algebra

Answer 1

The range is the set of y-coordinates of the function.

As per graph we can see:

• All positive values included as well as zero;
• There is one negative value, at y = - 2.

Add all together to get the range:

• y = - 2 and y ≥ 0

As interval the range is:

• y ∈ {-2} ∪ [0, + ∞)
