Question

I need to find the domain and the range in both of these graphs , I need help

Answer 1

The Domain of a function are all the values of x for which the function exists.

The Range are all the values of y that the function takes.

Then, we can see that in graph 1:

Domain: [0, 18]

Range: [200, 2000]

For graph 2:

Domain: [0, 4]

Range: [0, 160]
