Question

A part of exponential function fis graphed on the grid.

5
Which inequality best represents the domain of the part shown?
A x > 1
B y > 1
C X - 2
D Y > -2

Answer 1

The domain is the x-values used by the graph, so you want to see how your graph lines up with respect to the x-axis.

This graph starts out with an x-value of 2 (although it doesn't really use 2, since it's an open circle) and then continues to the right forever.

The domain is x > –2.
