Function rule
Take a look at the function:
\[f(x)=\left(x-9\right)\cdot \left(x-7\right)\cdot \left(x+7\right)\]
\[f(x)=\left(x-9\right)\cdot \left(x-7\right)\cdot \left(x+7\right)\]
We have #f(2)=315#. Here, the argument is equal to and the function value is equal to .
The function value is also called the .
The function value is also called the .
