1. The problem statement, all variables and given/known data Show that the function defined by (stepwise) f(x)= e^(-1/x^2) if x =/ 0 = 0 if x=0 is NOT equal to its Maclauren series. Then graph the function and comment on its behavior near the origin. 3. The attempt at a solution Well, I honestly don't know how to prove this. I graphed it and noticed that as it approaches the origin, it concaves up, so f''(x)>0 at (0,0). Am I supposed to first u-substitute in order to differentiate the e^(-1/x^2)?
