Answer:
3rd one
Step-by-step explanation:
Answer:
Yes, each x-value has a unique y-value.
Step-by-step explanation:
This is a function because each x-value has its own y-value. If this is not the case then it is not a function, because then, two points with the same x-value and different y-values would fail the VLT.
Your graph does not have overlaps and each x-value has a unique y-value
VLT
The vertical line test (VLT) is a <u>simple method that mathematicians made because</u><u> they were lazy</u><u> to make a table of values and find duplicates. </u>
<u />
- Passing the VLT means that if you drew a vertical line anywhere on the graph, it would only go through one point.
- Failing the VLT would mean that the vertical line
A quick way to check if it is a function is by looking for duplicates of x-values and check that the duplicates have the same y-value.

For this case, what we must do is calculate the mean of the given data.
For this, we must do the following:
Add the given numbers and divide by the number of numbers.
We have then:

From here, we clear the value of x.
We have then:
Answer:
Tasha would have to score 90 on the sixth test to have a mean of 85
Answer:
$11
Step-by-step explanation:
multiply $2 by four because they charge by hour and not by half hour. = 8
add $3 to 8. =11
Answer:
Domain = (1,3,5,8) and Range = (2, 4, 6, 9)
Step-by-step explanation:
Domain are sets of input values
Range are set of output values that have a corresponding values in the domain
From (domain, range)
Therefore, the domain are: (1,3,5,8)
Range are: (2,4,6,9
