Question

which diagram does not show a function?

Explanation:

Step1: Recall function definition

A function is a relation where each input has exactly one output.

Step2: Check each diagram

• Top-left: Each input maps to one output.
• Top-right: Each input maps to one output.
• Bottom-left: Each input maps to one output.
• Bottom-right: Input 1 maps to two outputs (-10 and -7), violating the function rule.

Answer:

The bottom-right diagram (Input 1 points to both -10 and -7; Input 4 points to -10 and 14) does not show a function.
