Given graph, what values of x is f(x) concave up?

Could someone explain to me how to find the values that is concave up or down if they give you a graph?

Is there a way to attach a picture to this question so a tutor could help me explain

Concave Up means the slope is increasing,  concave down the slope isdecreasing.

x^2 is concave up for entire domain.

-x^2 is concave down for entire doman.

x^3 is concave down until 0 and then concave up afterward.

I hope that helps...
