Start with the given function.

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

Evaluate to get 4.

Multiply -1 and -2 to get 2

Now combine like terms

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

Start with the given function.

Plug in . In other words, replace each x with -1.

Evaluate to get 1.

Multiply -1 and -1 to get 1

Now combine like terms

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

Start with the given function.

Plug in . In other words, replace each x with 0.

Evaluate to get 0.

Multiply -1 and 0 to get 0

Now combine like terms

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

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

Start with the given function.

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

Evaluate to get 9.

Multiply -1 and 3 to get -3

Now combine like terms

Now lets make a table of the values we have calculated

Now plot the points

Now connect the points to graph (note: the more points you plot, the easier it is to draw the graph)
