(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

f(x) = e^{x2}

find the range of f(x)

How do I do this - I don't know how to draw this graph?

g(x) = x^{2}+ 3e^{x2}

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) = 2xe^{x2}

Giving a min. point of 0

BUT THE ANSWER IS f(x) ≥1

Why does the min point method not work?
