To check: whether the graph is a function
Answer to Problem 29CCSR
Yes, the curve in a graph represents a function
Explanation of Solution
Given information: A graph is given.
Consider the following graph.
According to vertical line test, if every vertical line intersects the curve in a graph in at most one point then the curve in a graph represents a function.
First draw a vertical line in a given graph
In the given graph, it can be observed that the vertical line intersects the curve at just one point.
Therefore,
The curve in a graph represents a function.
