How do you find the critical points and the open intervals where the function is increasing and decreasing for #y = xe^(x(2 - 3x))#?
The function is increasing on the interval:
Jasivan S, gives an excellent answer to the question asked, but I suspect that the intended question was: Find the open intervals on which the function is increasing and those on which it is decreasing. (Rather than finding those on which it is doing both.)

To find the critical points and the intervals where the function is increasing or decreasing for ( y = xe^{x(2 - 3x)} ), follow these steps:
- Find the derivative of the function ( y ) with respect to ( x ), denoted as ( y' ).
- Set ( y' ) equal to zero and solve for ( x ) to find the critical points.
- Determine the intervals where ( y' > 0 ) to identify where the function is increasing.
- Determine the intervals where ( y' < 0 ) to identify where the function is decreasing.
Let's go through these steps:
- The derivative of the function ( y = xe^{x(2 - 3x)} ) can be found using the product rule and chain rule:
[ y' = e^{x(2 - 3x)} + x(e^{x(2 - 3x)})\cdot(2 - 3x) ]
- Set ( y' ) equal to zero and solve for ( x ) to find the critical points:
[ e^{x(2 - 3x)} + x(e^{x(2 - 3x)})\cdot(2 - 3x) = 0 ]
This equation may not have an explicit solution, so you may need to use numerical methods or graphing techniques to approximate the critical points.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
