Which direction does the graph of the equation shown below open?

v^2-4x+4y-4=0

A. Right

B. Down

C. Up

D. Left

Option A.

you can rewrite the equation as x = y^2 / 4 + y - 1

If you conserve the traditional x-axis and y-axis, the parabola opens to the right (the symetry axis is parallel to x and the function grows as y grows).
