What function is represented below?
graph begins in the second quadrant and decreases quickly while crossing the ordered pair negative 2, 1. when the graph enters the first quadrant, it begins to decrease slowly as it approaches the x axis.

f(x) = one fourth to the power of x plus 2
f(x) = one fourth to the power of x + 2
f(x) = one fourth to the power of x minus 2
f(x) = one fourth to the power of x − 2
