graph the relation in the table. then use the vertical-line test. is the relation a function? -1 & 3, 1 & -1, 2 & 2,
1 & 3
1 answer:
Answer:
this relation is not a function.
Step-by-step explanation:
Given relation is
(-1, 3) (1,-1) (2,2) and (1,3)
Now plot all the ordered pairs on the graph
Then we draw vertical lines through these points
If any vertical line crosses two points then this relation is not a function
The graph is attached below
We can see that the red vertical line crosses both points (1,-1) and (1,3)
It does not passes vertical line test.So this relation is not a function.

answer : An exponential function is much better fit because there is no fixed rate in the table
Step-by-step explanation:
An exponential function is much better fit because there is no fixed rate in the table attached but the values in the table keeps increasing exponentially, hence an Exponential function will be a better fit, But a linear function would be preferred only if there is a fixed rate
