Chapter 10.2, Problem 15AYU

In Problems 13-20, the graph of a parabola is given. Match each graph to its equation.

(A) $y^2\text{ = 4}x$     (C) $y^2\text{ = }-\text{4}x$     (E) ${\left(y-\text{ 1}\right)}^2\text{ = 4}\left(x-\text{ 1}\right)$     (G) ${\left(y-\text{ 1}\right)}^2\text{ = }-\text{4}\left(x-\text{ 1}\right)$

(B) $x^2\text{ = 4}y$     (D) $x^2\text{ = }-\text{4}y$     (F) ${\left(x+\text{ 1}\right)}^2\text{ = 4}\left(y+\text{ 1}\right)$     (H) ${\left(x+\text{ 1}\right)}^2\text{ = }-\text{4}\left(y+\text{ 1}\right)$
