1st step: distribute x(x-12) and then add 34
so you will now have y = x^2 – 12 x +34  or you could type in:
y = x(x-12) +34 without even distributing
Put either of those into Y1 and try answer (1) in Y2, like this…not a match!!  The tables are different as is the graph!

Now try answer (2) below  also not a match

Next, choice (3) nope not a match

Choice 4 below, the tables match and the graphs are exactly the same — therefore we can only see one parabola!  You just got 2 more points 🙂
