Let's evaluate f%283%29


f%28x%29=6x-1 Start with the given function.


f%283%29=6%283%29-1 Plug in x=3. In other words, replace each x with 3.


f%283%29=%2B18-1 Multiply 6 and 3 to get 18


f%283%29=17 Now combine like terms


-----------Now let's evaluate another value---------


Let's evaluate f%28-3%29


f%28x%29=6x-1 Start with the given function.


f%28-3%29=6%28-3%29-1 Plug in x=-3. In other words, replace each x with -3.


f%28-3%29=-18-1 Multiply 6 and -3 to get -18


f%28-3%29=-19 Now combine like terms
