PLEASE HELP I DON'T KNOW HOW TO SOLVE THIS.

Step-by-step explanation:

X is defined for all numbers on the domain starting at x=0. It doesn’t show or mention a cutoff/equation in the picture so it’s safe to assume it continues forever

To find the domain from the graph, you have to focus only x-axis because domain is the set of x-value.

From the graph, we can see that domain starts at x = 0 and keeps going and going positive infinitely. That means the domain must be greater or equal to 0.

Here is an easier way to understand

And if we combine both, we get

But we don't usually write positive infinity, therefore we convert to
