Answer:

The domain is the set of values you put into the function.

The range is the set of values the function outputs.

Example problem:

Find the range of this function: y = 2x + 3, x > 0

The x > 0 part is the domain, so this means that only positive values of x can be inputted in the function.

If only positive values can be inputted in the function, then the range will be: y > 3
