Problem:
What is the domain of the graphed function?
A) y ≥ 4
B) x ≥ -2
C) y ≥ -2
D) x ≤ -2
-------------------------------------------------------------------------------
Answer: choice B) x is greater than or equal to -2
-------------------------------------------------------------------------------
Reasoning:
The domain is the set of allowed inputs or x values. The x axis is what we'll focus on here. Notice that the left most portion of the curve stretches to x = -2. Draw a vertical line through this terminal point and you'll see it hitting -2 on the x axis. This is the furthest we can go to the left, so x = -2 is the smallest allowed input. Anything smaller and it's not allowed, which is why x must be -2 or larger, or
