Question

What is the domain and range of `y=2x-3`?

Answer 1

`x inRR,yinRR`

Explanation:

Since any value of `x` only gives one value of `y` ane each value of `y` has one corresponding `x` value, we don't have to place any limits.

Also, all values of `x` gives a value for `y`, and all values for `y` are possible, we say that domain is `x inRR` and the range is `yinRR`, where `inRR` which means it contains all values in the real set (`RR={0,-3,3.54,8.2223,1/3,e,pi,etc.}`)
