Best ResponseYou've already chosen the best response.0If you don't want a technical, overcomplicated definition, the range of a function is essentially the set of all values that the function can take: basically, the maximum and minimum height above and below the xaxis (or, alternatively, the greatest and least value on the yaxis). For a line with a slope not equal to (it's not horizontal), the range is from negative infinity to positive infinity...for a parabola, it's a finite value to the maximum or minimum point, and infinite in the opposite direction.
