[SOLVED] Error in this tangent line problem?
This is from a review section, and I am wondering whether there is a typo in the original problem itself or if I have forgotten something critical. Here is the problem:
"Find the point(s) on the graph of such that the tangent line at that point passes through the point (0,-9)."
Just thinking about the graph of , it would seem impossible for there to be a tangent which passes throught (0,-9). But just for good measure, I did the math:
Sure enough, there appears to be no real answer. Am I making a mistake, or is this a question without an answer?
