Graph of a function
mathematics, the graph of a function f is, formally, the set of all ordered pairs (x, f(x)), such that x is in the domain of the function f. In the common
Convex function
the graph of the function lies above or on the graph. Equivalently, a function is convex if its epigraph (the set of points on or above the graph of the
Function (mathematics)
variable of the function (one often says that f is a function of the variable x). A function is uniquely represented by its graph which is the set of all pairs
a topological space resembling a graph in the sense of discrete mathematics Graph of a function Chart, a means of representing data (also called a graph)
Periodic function
periods of the function. Geometrically, a periodic function can be defined as a function whose graph exhibits translational symmetry. Specifically, a function
Exponential function
exponential function also appears in a variety of contexts within physics, chemistry, engineering, mathematical biology, and economics. The graph of y = e x
Vertical line test
test is a visual way to determine if a curve is a graph of a function or not. A function can only have one output, y, for each unique input, x. If a vertical
Implicit function theorem
the graph of a function. There may not be a single function whose graph can represent the entire relation, but there may be such a function on a restriction
the tangent line to the graph of the function at that point. The tangent line is the best linear approximation of the function near that input value. For
Parent function
parent function of the family of quadratic equations. For linear and quadratic functions, the graph of any function can be obtained from the graph of the
