6 Types Of Functions In Math
- Constant Function
- Identity Function
- Modulus Function
- Polynomial Function
- Even Function
- Odd Functions
1. Constant Function
The constant function is a function f expressed in the formula f(x) = c, with x a constant. The graph is if painted in a coordinate axis where the x axis domains are parallel to the x axis.2. Identity Function
The identity function is a function expressed in the formula f(x) = x. The identity function is often expressed by the symbol I so that I(x) = x.Here is a graph of the identity function:
3. Modulus Function
The modulus function is a function f which contains the form of absolute value.Example of modulus function
Draw a function graph of f(x) = | 2x - 4 | !
Answer :
Draw the first graph y = 2x - 4, after which the graph lies beneath grow x, we are positive by reflecting the graph below the x axis with the mirror is the x axis.

4. Polynomial Function
The polynomial function is a function expressed in the form of :
If n = 1 then the linear function is formed (the graph is a straight line)
If n = 2 then the quadratic function is formed (the graph is parabolic)
5. Even Function
Even function is a function f where applicable f(x) = f(-x). Which is an even function, among others, the power-rank function of the variable is said to be even. If the function is a fraction, then it can be said even function if the variable on the numerator and the denominator are all or even all odd.6. Odd Functions
Odd function is a function whereby f(-x) = -f(x) is applied. Which is an odd function, among other functions that all variables are odd rank. If the function is a fraction, then it can be said an odd function if the variable is at the odd-numbered numerator and the variable of the denominator is even or vice versa.Similarly this article.
