Question

what is the domain of the graph?
$x \leq 0$
$x \geq 0$
$y \geq 0$
all real numbers

Explanation:

Step1: Define domain of a function

The domain of a function is the set of all possible input (x) values for which the function is defined.

Step2: Analyze the given graph

The graph shown is $y=x^2$, which extends infinitely to the left and right along the x-axis. There are no restrictions on the x-values that can be plugged into the function $y=x^2$.

Answer:

All real numbers
