You have to choices:
Either you make a table with x and y, and plot the resulting values
Or
You would graph the parent function
[tex]y=x^2[/tex]
then:
shift it to the left 4 units
and
shift it down 6 units
and
compress it vertically with factor of 2
I think this
would help you.
Feel free to ask
if you faced any difficulties...
