Properties of functions

Properties of functions

1. Table value

   • Is a list of numbers that are used to substitute one variable, such as within an equation of a line and other functions, to find the value of the other variable, or missing number.

2. Mapping diagram

   • shows how the elements are paired. Its like a flow chart for a function, showing the input and output values. A mapping diagram consists of two parallel columns.

3. function notation

   • It is meant to be a precise way of giving information about the function without a rather lengthy written explanation.

4. Ordered Pairs

   • a pair of elements a, b having the property that ( a, b) = (u, v ) if and only if a = u, b = v.

5. Graph

   • is the set of ordered pairs (x, y), where f(x) = y. In the common case where x and f(x) are real numbers, these pairs are Cartesian coordinates of points in the Euclidean plane and thus form a subset of this plane
