Question

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

Answer 1

Range of `y = (-oo,+oo)`

Explanation:

`y = 2x-2`

`y` is a straight line defined `forall x in RR`

`y` has no upper or lower bounds.

Hence, the range of `y = (-oo,+oo)`

This can be inferred from the graph of `y` below.

graph{2x-2 [-32.47, 32.48, -16.24, 16.23]}
