Please answer me its math question!

The graph of h(x)= |x-10| +6 is shown. on which interval is this graph increasing

The height of a flare fired from the deck of a ship in distress can be modeled by h(t)= -2(8t^2-52t-28), where h is the height of the flare above water and t is the time in seconds. a. find the time it takes the flare to hit the water.

If you answer 2+2 you will get over 80 points
