FUNCTIONS :
a function is a correspondence that pairs each element of a set with one element of another set.

CONSTANT FUNCTIONS
Given
f : A->B if f maps all the elements of set A to one and only one element of set B, this function is called as a constant functıon and donated by f(x) = c where c is a constant real number.
LINEAR FUNCTIONS
For any real numbers a and b, f :R->R , f(x)=y=ax+b is said to be linear functıon.
EVEN AND ODD
FUNCTIONS
-
f :R->R , for ∀ ∈x R;
If f(-x) = - f(x) then f is an odd function.
PIECEWISE
FUNCTION
Sometimes a function can’t be described by a single equation, and instead we have to describe it using a combination of equations.

GRAPHS OF
FUNCTIONS
The set of the points in the analytic plane corresponding to the elements of a function is the graph of
this function.
