If the x-value repeats and the y does not, is it a function?

Answer:

If X repeats and y does not it is not an example of a function. But if the y repeats and has two different x values that can be known as a function.

For an example ( 1 , 3) and (1, 4) thats not an example of a function because the x value is repeating but if its ( 1, 4) and (2,4) a thats

a function because no x value is repeating the x value is known as an independent value. Does that make sense?

"This relation is definitely a function because every x-value is unique and is associated with only one value of y. So for a quick summary, if you see any duplicates or repetitions in the x-values, the relation is not a function."

If an x-value in a relation repeats, the y-value must also repeat for that x-value to make the relation to be defined as a function.

For a relation to be called a function, the following holds true:

Each x-value (input) has it's own unique y-value (output).

A x-value cannot give two different y-values.

If an x-value repeats, the corresponding y-value must repeat.

Therefore, if the x-value in a relation repeats, the y-value must also repeat for that x-value for the relation to be defined as a function.

Leo has purchased a fee-for-service health insurance plan from Leroux Health Insurance. Plan A includes a $225.00 monthly premium and an annual deductible of $5,500.00 (not including co-pays). Except for chronic back pain, Leo is a fairly healthy man. He visits his primary care physician four times a year on scheduled visits. He sees a chiropractic specialist every two weeks to help with his lower back pain. He has no current prescriptions that need refilling regularly. Assuming Leo maintains his regular visits with his primary care physician and his chiropractor, and avoids any trips to the emergency room or urgent care, how much will Leo pay in health care related fees this year, including his premium payments?

An air-conditioning repair technician claims to complete 67% of repairs in under an hour. A random sample of 31
repairs was chosen, and 22 of those were completed in under an hour. Let p = the proportion of the random
sample that were completed in under an hour.
The probability that 71% or more of this technician's repairs were completed in under an hour is 0.317. Does this
result provide convincing evidence against the technician's claim?
Yes, it is expected that 22 of the units at most will be repaired in under an hour.
Yes, the probability of seeing the sample result is so far from what is expected that the probability of it occurring by
chance alone is very unlikely.
No, there is a very small chance of seeing the sample result. It is unlikely to occur by chance alone.
No, the difference between the sample result and what is expected is not extreme enough. The probability of it
occurring by chance alone is not unlikely.
