Question 183487
How do I graph this problem?  {{{ y = x^2 - 2x - 8? }}}
--------------------
Manually, make a table of x and y.
Write values of x, say from -4 to +4 (integers), and find the y for each one.
Then plot the points and draw a smooth line thru them.  If it helps, add points such as x = 2.5, 3.5, etc
