SOLUTION: For the function f(x) Determine the range of f for this equation. Write range in interval notation f(x)= {2x-3 if x≤1 { x+1 if x>1

Algebra ->  Functions -> SOLUTION: For the function f(x) Determine the range of f for this equation. Write range in interval notation f(x)= {2x-3 if x≤1 { x+1 if x>1      Log On

Here's the graph:

 

I'll draw the range on the y-axis in green:

 

The RANGE is the part of the y-axis that is BESIDE the graph:

Range:  (-∞,-1] U (2,∞)
