Let's evaluate

Start with the given function.

Plug in . In other words, replace each x with -2.

Multiply 5 and -2 to get -10

Now combine like terms

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

Let's evaluate

Start with the given function.

Plug in . In other words, replace each x with 3.

Multiply 5 and 3 to get 15

Now combine like terms
