In order to graph , we need to plot some points.
So we can start at any x value. So lets start at x=-5

Start with the given equation

Plug in

Calculate the f(x) value
So when

So our 1st point is (-5,-19)

Start with the given equation

Plug in

Calculate the f(x) value
So when

So our 2nd point is (-4,-15)

Start with the given equation

Plug in

Calculate the f(x) value
So when

So our 3rd point is (-3,-11)

Start with the given equation

Plug in

Calculate the f(x) value
So when

So our 4th point is (-2,-7)

Start with the given equation

Plug in

Calculate the f(x) value
So when

So our 5th point is (-1,-3)

Start with the given equation

Plug in

Calculate the f(x) value
So when

So our 6th point is (0,1)

Start with the given equation

Plug in

Calculate the f(x) value
So when

So our 7th point is (1,5)

Start with the given equation

Plug in

Calculate the f(x) value
So when

So our 8th point is (2,9)

Start with the given equation

Plug in

Calculate the f(x) value
So when

So our 9th point is (3,13)

Start with the given equation

Plug in

Calculate the f(x) value
So when

So our 10th point is (4,17)

Start with the given equation

Plug in

Calculate the f(x) value
So when

So our 11th point is (5,21)

Now lets make a table of the values we have calculated

Now plot the points

Now connect the points, this is the graph of
