There are two critical points, at
Explanation:
Since the derivative is already given, all we must do is solve the equation
#e^x(x^2 + 2x) = 0#
Step 1: solving
This has no solution, because if you take the natural logarithm of both sides, you get
#ln(e^x) = ln0#
And
Step 2: solving
We have:
#x(x + 2) = 0#
#x = 0 or -2#
These are our two critical numbers.
Hopefully this helps!
