2+16 defined on the interval (-5,5) , F(x) is concave up on what regions? F(x) is concave down on what regions? What is the maximum and minimum value?...

For the function f(x) = x√x^2+16 defined on the interval (-5,5) , F(x) is concave up on what regions? F(x) is concave down on what regions? What is the maximum and minimum value?

PS: I am struggling to answer the question so I need help to understand how the work is done, this is what paid tutoring services are for otherwise help me revise the question! Please don't cite academic dishonesty when i have asked such questions before that have been answered!
