# What is the domain and range of #y= 1/2x#?

graph{y=1/2x [-10, 10, -5, 5]}

Domain: all real numbers or

using interval notation: (-infinity, infinity)

Range: all real numbers or

using interval notation: (-infinity, infinity)

If you look at the graph, you will see that all x-values are included in the domain, which is the set of all x-values.

If you look at the graph, you will see that all y-values are included in the domain, which is the set of all y-values.

The domain of the function y = 1/2x is all real numbers except x = 0, since division by zero is undefined. The range of the function is also all real numbers, as the output (y) can take on any value depending on the input (x).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
