Question 46590: please help.
Let .f(x)= x+2 if -3<=x<0
x^2 + 1 if 0 <=x<=2
a. Evaluate each of the following
f(-1) = ______ f(0) = ______ f(2) = ______
b. What is the domain of f(x)?


c. Sketch the graph of y = f(x) on the set of axes

You can put this solution on YOUR website!
f(x) = x + 2
f(-1) = -1 + 2 = 1
f(-1) = 1
f(0) = 0^2 + 1 = 1
f(0) = 1
f(2) = 2^2 + 1 = 5
f(2) = 5
Domain: {x|2%3E=x%3E=-3}
