Find y max
Here is how I'm approaching this ...
With 3 being a critical point
So the critical point is a maximum. It's a parabola opening downward from 3?
Thank you for clarifying. I'm prone to making mistakes and that is why I like to double check. Looking at the equation is still seems 3 is our critical point, but the differences in our y' will become ...
Which should still give us 3 as our maximum with a downward opening parabola. I appreciate the help as this mistake could have cost me in other equations
The equation wanted "y max," not "x max" so technically it is is correct. I'm doing these equations with a multiple choice solution set and he has
d.)none of these
I originally picked b because I was thinking of in terms of x, but in the context of "find y max" . Evil questions. Thanks for catching that
