Question

How do you find the domain and range for `y=-1/2x+3`?

Answer 1

Domain: `(-oo, +oo)`
Range: `(-oo, +oo)`

Explanation:

For any linear function of the form `y=mx+b` the domain and range is the set of all real numbers because, a line extends infinitely in both directions.

Kindly see the graph of `y=-1/2x+3`.

graph{y=-1/2x+3[-20,20,-10,10]}

God bless....I hope the explanation is useful.
