Question

Look at the graph below and use the vertical line test to determine whether or not the graph represents a function. The determine if it is a one-to-one function.positive cube root functionThis graph Answer represent a function.This graph Answer represent a one-to-one function.

Answer 1

By using the vertical line test with the given graph

Since a vertical line can intersect the graph in any position in only ONE point

Then the graph represents a function

To test if it is a one-one function, draw a horizontal line and check if it intersects the graph at any position in only ONE point or not

Since a horizontal line can intersect the given graph in only ONE point in any position, then

The graph represents a one-one function
