Question 944842: How do I graph the following piece meal equation?
f(x)= -2 if x less than or equal to -1
x-1 if -1
-3 if x>1
What I sketched was:
a closed dot at (-1, -2) with a line going to infinity to the left
an open dot at (-1, -2), a closed dot at (1,1) with a line in between the two and
an open dot at (1, -3) with a line going to infinity to the right;
I received a 1.9 out of 2 possible points. I need to get 100% before I can move on to my next lesson. What did I do wrong?
