1. The problem statement, all variables and given/known data f(x) = ex2 find the range of f(x) How do I do this - I don't know how to draw this graph? g(x) = x2 + 3ex2 Again, how is this done without drawing the graph? 2. Relevant equations 3. The attempt at a solution so for the first graph, for example, I differentiated it dy/dx for f(x) = 2xex2 Giving a min. point of 0 BUT THE ANSWER IS f(x) ≥1 Why does the min point method not work?
