Homework Statement
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?
Homework Equations
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?
