To determine if the graph represents a function, we can use the vertical line test. This means if we can draw a vertical line at any x-value, and it only intersects the graph at one point, then the graph is a function. If a vertical line intersects the graph at more than one point, then it is not a function.
Since I can't see the actual graph you're referring to, here’s how you can analyze it:
-
Apply the Vertical Line Test: Examine the graph carefully. Draw (or imagine) vertical lines at various x-values. If any vertical line crosses the graph more than once, then the graph is not a function.
-
Find the Domain: The domain includes all the possible x-values that are represented on the graph. Look for the leftmost and rightmost points of the graph to determine the range of x-values.
-
Find the Range: The range includes all the possible y-values from the graph. Look for the lowest and highest points on the y-axis to determine the range of y-values.
If you provide me with a description of the graph or its key characteristics (e.g., whether it intersects itself, if it's a line, parabola, etc.), I can give you a more specific answer regarding whether it's a function and what the domain and range are.
