Question 364545: Find a piecewise definition of "f" that does not involve the absolute value function. Sketch the graph of "f", and find the domain, range, and the values of X in the domain of "f" at which "f" is discontinuous.
fx = 2 - |x|

f%28x%29=2x-1 when x%3C3
f%28x%29=1 when x%3E=3

Domain: (-infinity,infinity)
Range: (-infinity,1]
f%28x%29 is discontinuous at x=1.
