Question 199555
graph the function f(x)=(-1/9)(x+2)(x-6)+5 in standard viewing on your calculator
<pre><font size = 4 color = "indigo"><b>
Press  Y=

After \Y1= type  (-1/9)(X+2)(X-6)+5

Press ZOOM

Press 6

You see something like this:

{{{graph(400,350,-10,10,-10,10,(-1/9)(x+2)(x-6)+5)}}}

If you want it centered, you notice that the middle of
the graph is about where 2 is on the graph, so we 

press WINDOW

Change the first two numbers so that it reads like this:

WINDOW
 Xmin=-8
 Xmax=12
 Xscl=1
 Ymin=-10
 Ymax=10
 Yscl=1
 Yres=1

Now press GRAPH.

Now you see something like this:

{{{graph(400,350,-8,12,-10,10,(-1/9)(x+2)(x-6)+5)}}}
