Sketch the graph of the function: f(x) =

{x^2 if x < -3

{x+12 if x >= -3

I'm not really sure what it wants, just like the graph for x^2, and x+12 ?, that's easy enough, but the "if" statements are throwing me off.

First, graph y= x

Now, because it says "x

Now draw the graph of y= x+12.

Then, because it says "if x>= -3", erase the part of that graph to left of x= -3.

What you have left is the graph of f (as a check, since (-3)
