Question

question which of the following graphs represent functions? select all that apply. select all that apply: figure a figure b figure c figure d

Explanation:

Step1: Recall vertical - line test

Use the vertical - line test. If a vertical line can be drawn anywhere on the graph and it intersects the graph at most once, the graph represents a function.

Step2: Analyze Figure A

For Figure A, any vertical line will intersect the graph at most once. So it is a function.

Step3: Analyze Figure B

For Figure B, any vertical line will intersect the graph at most once. So it is a function.

Step4: Analyze Figure C

For Figure C, a vertical line can be drawn such that it intersects the graph at more than one point. So it is not a function.

Step5: Analyze Figure D

For Figure D, a vertical line can be drawn such that it intersects the graph at more than one point. So it is not a function.

Answer:

A. Figure A, B. Figure B
