Q1. Determine if the function represented by the graph is even, odd, or neither. Explain why.

Background

Topic: Symmetry of Functions

This question tests your understanding of how to classify functions as even, odd, or neither based on their graphical symmetry.

Key Terms:

• Even Function: A function is even if for all in the domain. Its graph is symmetric about the y-axis.

• Odd Function: A function is odd if for all in the domain. Its graph is symmetric about the origin.

• Neither: If a function does not satisfy either condition, it is neither even nor odd.

Step-by-Step Guidance

1. Examine the graph and look for symmetry about the y-axis (vertical axis). If the graph is a mirror image on both sides of the y-axis, the function may be even.

2. Check for symmetry about the origin. If rotating the graph 180 degrees about the origin results in the same graph, the function may be odd.

3. If neither symmetry is present, the function is neither even nor odd.

4. Use the definitions above to justify your answer based on the graph's appearance.

Q2. Determine if the function represented by the graph is even, odd, or neither. Explain why.

Background

Topic: Symmetry of Functions

This question is similar to Q1 and tests your ability to identify even, odd, or neither functions from their graphs.

Key Terms:

• Even Function:

• Odd Function:

• Neither: Does not satisfy either condition.

Step-by-Step Guidance

1. Look for y-axis symmetry (even) or origin symmetry (odd) in the graph.

2. Compare the left and right sides of the graph relative to the y-axis.

3. Consider whether the graph looks the same after a 180-degree rotation about the origin.

4. Use these observations to classify the function.
