Question

the graph shows part of an exponential function.
which inequality represents the domain of the part shown?
$x > 0$
$x \geq 1$
$y \leq 8$
$y > 1$

Explanation:

Step1: Recall domain definition

Domain is set of all x - values. So we focus on x, eliminate y - related options (y ≤ 8, y > 1).

Step2: Analyze graph's x - values

The graph starts at x = 1 (closed dot, so inclusive) and goes to the right. So x ≥ 1. The option x > 0 is incorrect as the graph starts at x = 1, not just x > 0.

Answer:

x ≥ 1 (the option with text "x ≥ 1")
