About this worksheet
Each worksheet has 6 problems determining if a graph shows a function.
This worksheet is designed to help children identify functions in mathematical graphs. It features six problems which challenge young minds to interpret equation-based graphs such as y-1 = -x, -y = x1, and others. Besides, it can be customized to meet specific learning needs, be easily converted into flash cards for interactive learning, or be used in a distance learning context to reinforce mathematical concepts.
Student objectives
- Decide whether a graph represents a function by checking if each x-value matches only one y-value.
- Use the vertical line test to spot graphs that are not functions.
- Identify repeated x-values on a graph and explain why that breaks the function rule.
Everyday practice
- Checking whether a conversion chart (like inches to centimeters) gives exactly one output for each input.
- Looking at a distance-time graph and deciding if each time has only one distance value.
- Reading a phone battery graph and checking if each time corresponds to one battery percent.
- Comparing a price-per-pound chart at a grocery store to see if each weight has one total price.
