I'm not good with any math that is above per algebra sorry.
The shapes of the 2 graphs are the same. However, because x has a fractional coefficient between 0 and 1, the period of the graphed function is twice as long (that is, 2pi instead of pi), and the graph has been reflected about the x-axis and then stretched vertically by a factor of 3.
C because one x-value can ONLY have one corresponding y-value. It cannot have more than one.
They intersect at point...
