Question

g(x)=x*√(x+3) Find local maximum or minimum.

Answer 1

Local maxima and minima on a graph look like little humps. Those humps are the points where it's turning around the other direction, so their slopes are 0. To find these, you can take the derivative of your graph and set it equal to 0 and solve for the x values that correspond to those places. I hope that makes sense.

Answer 2

I know, but the thing is, I'm not sure if my answer is correct or not.
