The table shows the outputs, y, for different inputs, x:
input (x)
6
12
15
25
output (y)
14
15
15
16

part a: do the data in this table represent a function? justify your answer. (3 points)

part b: compare the data in the table with the relation f(x) = 7x − 15. which relation has a greater value when x = 6? (2 points)

part c: using the relation in part b, what is the value of x if f(x) = 6? (5 points)

Solve the word problem. the table shows the low outside temperatures for monday, tuesday, and wednesday. by how many degrees did the low temperature increase from monday to tuesday? this function table shows the outside temperature for a given a. 21.1⁰ b. 8.6⁰ c. 4.9⁰ d. 3.9⁰(the picture is the graph the the question is talking about.)

A. find the power of the test, when the null hypothesis assumes a population mean of mu = 450, with a population standard deviation of 156, the sample size is 5 and the true mean is 638.47 with confidence intervals of 95 b. find the power of the test, when the null hypothesis assumes a population mean of mu = 644, with a population standard deviation of 174, the sample size is 3 and the true mean is 744.04 with confidence intervals of 95% c. find the power of the test, when the null hypothesis assumes a population mean of mu = 510, with a population standard deviation of 126, the sample size is 10 and the true mean is 529.44 with confidence intervals of 95

:)i need to know on which ones are corresponding, alternate interior, alternate exterior, or none of these.
