Questions & Step-by-Step Solutions
Which of the following best describes a function that is one-to-one?
Steps
Concepts
Step 1: Understand what a function is. A function takes an input and gives an output.
Step 2: Know that in a one-to-one function, each output is linked to only one input.
Step 3: Visualize this with a graph. If you draw a horizontal line across the graph, it should only touch the graph at one point for each output.
Step 4: If a horizontal line touches the graph at more than one point, the function is not one-to-one.
