A. The equation 
represents vertical line. This is not a function, because one element x=5 is associated to all (not one) elements of 
B. The equation 
represents parabola that goes in positive x-direction. This is not a function, because each 
is associated to two different y. For examlpe, when x=10, then 
C. The equation 
represents parabola that goes in positive y-direction. This is the function, because for each x is associated only one y.
D. The equation 
represents hyperbola. This is not a function, because for one x there are two different possible y.
