To explain: The logic behind the vertical test for the graph of function.

Answer to Problem 35E
A function gives a unique value for each value of
Explanation of Solution
Given information: The vertical line test is used to check that whether a curve is the graph of a function or not: If every vertical line in the
According to the definition of a function is a curve that gives a unique functional value for every value of
So, a function gives a unique value of
Therefore, a vertical line intersects the curve at only one point if it is a function.
