## Algebra and Trigonometry 10th Edition

This conic is a parabola opening to the right. Notice from the graph that the vertex of the parabola is shifted 2 left and 1 up. This can be verified from the equation. $(y-1)^2=4(2)(x+2)$ The $(x+2)$ means that the vertex is shifted two units left (across the x-axis). The $(y-1)$ means that the vertex is shifted up one unit (up the y-axis).
