How do you find the critical points to sketch the graph #y=x(x+2)^2#?
Please see below.
A critical number for a function
# = (x+2)[(x+2)+2x)#
# = (x+2)(3x+2)#
The critical numbers are
If you have been taught that critical point is the same as critical number , then you are done.
You will answer: the critical points are
If you have been taught that a critical point is a point on a graph , then you still need to find the corresponding
So you will answer: the critical points are
