Which of the following equations is of a parabola with a vertex at (1, 2)? 1.)y = (+ 1)2-2
2.) y = (x - 1) 2-2
3.)y=(x + 1)2 + 2
4.)y = (x - 1) 2 + 2

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.

Ihave, but this question is gonna probably get deleted.

You do 1.25in times 15in and get 18.75in squared
