Give answers using interval notation for x. Part 3: By looking at the behavior of f"(x) what does that tell us about our f(x) function? Again, use interval notation in your answer. Part 4: Use desmos or another graphing utility to graph f, f' and f\" all on the same grid each in a different labeled color. Be sure to have an efficient graphing window.
