• natural numbers

Which of the following type of function that does NOT just set the domain and range

as a real numbers but also have conditions?

• constant function

• linear function

• radical function with odd index

• rational function

How do we evaluate a function?

• by finding the value to be substituted to the variable

• by solving for the value of the variable that will make the function equal to 0

• by substituting the given value of the variable and simplifying

• by graphing the function on the Cartesian plane

It is a tool that helps determine points which can be used in creating a graph.
