Linear and Polynomial Functions
Constant-has the form f(x)=c, where c is any real number. Its graph is a horizontal line. When c=0, f(x) is the zero function.
Identity- f(x)=x passes through all points with coordinates (a,a).
Quadratic-f(x)=x^2, has a U shaped graph.
Cubic- f(x)=x^3 is symmetric about the origin.
Square root function- f(x)= Square root of x
Reciprocal function- f(x)=1/x
Absolute Value Function- f(x)=|x|
Integer function- f(x)=[[x]]
Reciprocal function- f(x)=1/x
Absolute Value Function- f(x)=|x|
Integer function- f(x)=[[x]]
