Do you want to graph?

In order to graph , we need to plot some points. To do that, we need to plug in some x values to get some y values

So let's find the first point:

Start with the given function

Plug in

Raise -3 to the 2nd power to get 9

Multiply 1 and 9 to get 9

Add 9 and 2 to get 11

So when , we have

So our 1st point is (-3,11)

-------------- Let's find another point --------------

Start with the given function

Plug in

Raise -2 to the 2nd power to get 4

Multiply 1 and 4 to get 4

Add 4 and 2 to get 6

So when , we have

So our 2nd point is (-2,6)

-------------- Let's find another point --------------

Start with the given function

Plug in

Raise -1 to the 2nd power to get 1

Multiply 1 and 1 to get 1

Add 1 and 2 to get 3

So when , we have

So our 3rd point is (-1,3)

-------------- Let's find another point --------------

Start with the given function

Plug in

Raise 0 to the 2nd power to get 0

Multiply 1 and 0 to get 0

Add 0 and 2 to get 2

So when , we have

So our 4th point is (0,2)

-------------- Let's find another point --------------

Start with the given function

Plug in

Raise 1 to the 2nd power to get 1

Multiply 1 and 1 to get 1

Add 1 and 2 to get 3

So when , we have

So our 5th point is (1,3)

-------------- Let's find another point --------------

Start with the given function

Plug in

Raise 2 to the 2nd power to get 4

Multiply 1 and 4 to get 4

Add 4 and 2 to get 6

So when , we have

So our 6th point is (2,6)

-------------- Let's find another point --------------

Start with the given function

Plug in

Raise 3 to the 2nd power to get 9

Multiply 1 and 9 to get 9

Add 9 and 2 to get 11

So when , we have

So our 7th point is (3,11)

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)
