# For the following function....

f(x)= -x+1    if -1<= (read this as less than or equal to) x<1

f(x)= 2         if x=1

f(x)= x^2.    if x>1

a) find f(0)

b) find f(1)

c) find f(2)

d) determine Domain and Range

This is a piecewise function, meaning that each part of the graph has a unique relationship.

You have to evaluate f(x) at x=0 , x=1 , and at x=2.  So you need to evaluate f(x) at different domains.

at x=0 , use the part with the interval -1≤x≤1
at x=1 , use the part with the interval x=1
at x=2 , use the part with the interval x>1
