Question

how do you find the domain on this type of graph

Answer 1

Answers:

Domain:  $x \ge -5$

Range:  $y \ge -2$

========================================

Explanation:

The domain is the set of all allowed x values of a function. The point on the very left shows that x = -5 is the smallest value possible. So this means the domain consists of x values such that x = -5 or x > -5. We shorten that to $x \ge -5$

------------------

The range is the set of possible y outputs. The lowest point is when y = -2 meaning that $y \ge -2$ is the range (so y can be -2 or larger).
