Functions

Here is a list of Functions.

 $f\left(x\right)\ =\ \parallel x\parallel\ \ \ \rightarrow\ Greatest\ Integer\ Function$  
 $f\left(x\right)\ =\ \left|x\right|\ \ \ \rightarrow\ \ Absolute\ Value\ Function$  
 $f\left(x\right)\ =\ x^3\ \ \ \rightarrow\ \ Cubic\ Function,\ 3$  
 $f\left(x\right)\ =\ x^2\ \ \ \rightarrow\ \ Squaring\ Function,\ 2\ \ \ Quadratic$   $f\left(x\right)\ =\ x\ \ \ \rightarrow\ \ Identity\ Function,\ 1\ \ \ Linear$  
 $f\left(x\right)\ =\ c\ \ \ \rightarrow\ \ CONSTANT\ Function,\ Linear$   $f\left(x\right)\ =\ ax\ +\ b\ \ \ \rightarrow\ \ Linear\ Function$  
 $f\left(x\right)\ =\ \sqrt{x}\ \ \ \rightarrow\ \ \ Square\ Root\ Function$  
 $f\left(x\right)\ =\ 1\ \div\ x\ \ \ \rightarrow\ \ Reciprocal\ Function$

Is the relation a function? Why.

• Yes, because the x-value 11 has two y-values pair with it.
• Yes, because each x-value has only one y-value paired with it.
• No, because the x-value 11 has two y-values pair with it.
• No, because each x-value has only one y-value paired with it.
