Using the function definition, it is found that the correct option is:
C. No, because a vertical line can be drawn that intersects the graph more than once.
--------------------------
- In a function, each value of the input x can have only one respective output y.
- In a graph, for a value of x, there can only be one value of y.
- To verify this, we trace a vertical line, and if it intercepts the function more than once, the graph is not a function.
- In the picture at the end, it can be seen that multiple vertical lines intersect the function twice, thus, not a function, and the correct option is C.
