    FUNCTION Functions is a focal concept of extreme importance in modern mathematics is the idea of functions.  Functions, which deal with corresponding relationship between the elements of two sets, are useful concepts throughout the mathematics curriculum. We can use tables to represent functions by listing the input values in one column and the corresponding output values in another column. Ordered pairs can be used to show the position on a graph, where the "x" (horizontal) value is first, and the "y" (vertical) value is second. Read the example of ordered pairs put in a table in

    •The first set of ordered pairs is said to be a function if no two ordered pairs have the same first coordinates with different second coordinates for example ( -1, 2), ( 1, 0), (2, 1) . The second example is not a function, because it contains the ordered pairs (1,2) and (1,4(-1, 4)). the first set is repeated . These have the same first coordinate and different second coordinates. Read the details about the set of ordered pairs in

    Here are example of equation that represent a function

    1.F(x) = X + 1

    2.H(x) = x^2 + 5x

    3.G(x) = x^2 -1

    Here are example of equation does not represent function

    1.Y^2 = x+5

    2.3y^2 = 4x +1

    3.y^2 = 4x+1
