Question

What is the range of the function `f(x) = 2x-5`?

Answer 1

The range is all real numbers. `R:{y:(y=R)}`

Range is the set of all possible `y` values for a function. The function `y=2x-5` is a line graphed below:
graph{2x-5 [-10, 10, -5, 5]}

The line extends forever in both directions and is uninterrupted.
