I need to know if it’s a function and explain how it is. please help!

Yes, because it passes the vertical line test. If we were to draw a vertical line anywhere on the graph, it would only go through one point, so the relation is a function.

Step-by-step explanation:

1. This graph is a function because it passes the vertical line test. The vertical line test is a simple method that is used to determine if a relation is a function or not. A function can one output (y) for every unique input (x). If we were to draw a vertical line anywhere on the graph, and it would only go through one point, then the relation is a function. If it went through multiple points in some areas, it's not a function.

2. Since we can draw a vertical line anywhere and have it pass through one point, this relation is a function.

1^3 + 2^3 + 3^3 +4^3 = (1+2+3+4)^2

i am only able to answer the first part. i am not sure about the second part. sorry
