We can't draw graphs for you here. You will have to get some graph paper and draw your own. It will be good practice for you.
The first equation has a local maximum or minimum at x = + or - sqrt(5/6)
The second funtion has a local maximum or minimum at x = + or - sqrt(2/3)
When you draw the curves you will see which are maxima or minima. Both have one of each.
