First, we have to figure out what our new equation is.
- 00:34
Since our new equation is the sum of x squared and 1, we have... x squared plus 1.
- 00:41
Remembering our translations and transformations of parabolas...
- 00:47
...we know that the "plus 1" just translates the entire parabola

of y = x2 up vertically 1 unit.
- 00:55
Sure looks like answer A to us.
