Does this graph represent a function? Why or why not?
A. No, because it fails the vertical line test.
B. No, because it is not a straight line.
C. Yes, because it is a curved line.
O D. Yes, because it passes the vertical line test.
As long as it passes the vertical line test, it represents a function. It does not matter whether it's curved or not, as long as there are not two lines over the imaginary vertical lines that go through the function.
