Answer:

The answer is A. You need to perform the vertical line test on it in order to solve.  If you draw a vertical line on it it will pass the line at only one point,

Step-by-step explanation:

Using the function concept, it is found that graph A represents y as a function of x.

--------------------------

  • A relation represents a function only if each value of the input is related to one value of the output.
  • In a graph, it means that for each value of x(horizontal axis), there can only be one respective value of y(vertical axis), that is, points cannot be aligned vertically.
  • In graphs B, C and D, for some values of the input x, there are multiples values of y, that is, there are points aligned vertically, and thus, they are not functions.
  • In graph A, for each input, there is only one output, thus, it is a function, and is the correct option.
