1. The graph is a parabola.
2. The parabola opens up, because there's no negative number in front of
.
3. The vertext is (5,-1), because of the vertex form.
This means that that -1 will be the least y-value used on the graph and the garph will open up from there.
The range is (-1, infinity) or { y | y > -1 }.
7x, 4y, 1are the terms, and 7x is the leading term.
