I suck at graphs....can anyone show me what they got for this cos im not really sure if mine is right...

A curve has the following features:
When x = -5, 0 and 3, y’ = 0
y" > 0 for x < -2 ½ and x > 1 ½
y” < 0 for -2 ½ < x < 1 ½
Give a possible sketch of the graph.

It has the turning points at x=-5, 0 and 3
If y''>0, then the turning point is a minimum
If y''<0 then the turning point is a maximum

Hence according to the information
x=-5 is a min tp
x=0 is a max tp
x=3 is a min tp

So the graph should have this shape
