If the domain and range of a function consists of real numbers, then you can graph it by plotting all ordered pairs (x, f(x)). Remember "y" = f(x). How can you tell by looking at a graph if it represents a function?

Let f(x) be a twice differentiable function (i.e. f(x), f′(x) and f′′(x) are defined for all x), and let a ∈ R (a is a real number). If f′(a) = 0 and f′′(a) > 0, then a is a strict local minimum of f. (a) Express the
