Determine whether the graph represents y as a function of x. Explain your answer. (a) -2 y 2 4 Yes, the vertical line test shows that the graph represents y as a function of x. Yes, the horizontal line test shows that the graph represents y as a function of x. No, the vertical line test shows that the graph does not represent y as a function of x. No, the horizontal line test shows that the graph does not represent y as a function of x. There is no way to determine this using the graph. (b) -6 2 2 4 Yes, the vertical line test shows that the graph represents y as a function of x. Yes, the horizontal line test shows that the graph represents y as a function of x. No, the vertical line test shows that the graph does not represent y as a function of x. No, the horizontal line test shows that the graph does not represent y as a function of x.
