In mathematics, the graph of a function f {\displaystyle f} is the set of ordered pairs ( x , y ) {\displaystyle (x,y)} , where f ( x ) = y . {\displaystyle...

The graph of a cubic function always has a single inflection point. It may have two critical points, a local minimum and a local maximum. Otherwise, a cubic...

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...

a real-valued function is called convex if the line segment between any two distinct points on the graph of the function lies above or on the graph between...

term linear function refers to two distinct but related notions: In calculus and related areas, a linear function is a function whose graph is a straight...

of the graph. The graph of a function with a positive second derivative is upwardly concave, while the graph of a function with a negative second derivative...

differentiation. Geometrically, the derivative at a point is the slope of the tangent line to the graph of the function at that point, provided that the derivative...

periods of the function. Geometrically, a periodic function can be defined as a function whose graph exhibits translational symmetry, i.e. a function f is...

curvature changes sign. In particular, in the case of the graph of a function, it is a point where the function changes from being concave (concave downward)...

advantage of drawing a graph of sine and cosine functions. This can be done by rotating counterclockwise a point along the circumference of a circle, depending...

of a single variable at a chosen input value, when it exists, is the slope of the tangent line to the graph of the function at that point. The tangent...

In mathematics, a saddle point or minimax point is a point on the surface of the graph of a function where the slopes (derivatives) in orthogonal directions...

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...

injective function (also known as injection, or one-to-one function ) is a function f that maps distinct elements of its domain to distinct elements of its...

in calculus, a stationary point of a differentiable function of one variable is a point on the graph of the function where the function's derivative is...

(Rademacher's theorem). When we try to draw a general continuous function, we usually draw the graph of a function which is Lipschitz or otherwise well-behaved...

the graph of a function. Although implicit in the development of calculus of the 17th and 18th centuries, the modern idea of the limit of a function goes...

real number such that, for every pair of points on the graph of this function, the absolute value of the slope of the line connecting them is not greater...

given a graph G = (V, E), a vertex labeling is a function of V to a set of labels; a graph with such a function defined is called a vertex-labeled graph. Likewise...

-intercept or vertical intercept is a point where the graph of a function or relation intersects the y {\displaystyle y} -axis of the coordinate system. As such...
