2. I assumed you were on the x-y plane

If you are just on a number line, put an open circle at x=3, then draw in the line to the left of that with an arrow at its end point.

graph is a piecewise; f(x)= 1) 2-2x-x^2, x=0. Determine whether graph has a tangent at x=o. If it does not, explain why not. I have no idea. When I plug in x=0, both equations give 2, but answer key says it does not exist.
