# Math Help - finding domain and range

1. ## finding domain and range

for the problem y = abs( x+2 ) - 3

i understand the vertex is (-2, -3)

is there also a domain and range?

i don't there is....

2. Domain is $(-\infty,\infty)$, range is $[-3,\infty)$.

What an odd question. If it exists, there is a Domain and a range.

i don't [think] there is....
What an odd-er conclusion.

Domain - What can you put in? Start with All Real Numbers and rule things out. In this case, nothing is ruled out.

Range - What can you get out? Start with All Real Numbers and rule things out. In this case, that absolute value is NEVER negative. The very least you can get from that absolute value is zero (0). This makes the minimum value of the entire expression -3. We just ruled out everything less than -3.
