1. Let T = {(1, 2), (1, 3), (2, 5), (3, 6), (4, 7)}. T : X ->
Y. X = {1, 2, 3, 4}, Y = {1, 2, 3, 4, 5, 6, 7}
a) Explain why T is or is not a function.
b) What is the domain of T?
c) What is the range of T?
d) Explain why T is or is not one-to one?

Using R and the data in the table below, perform the regression
of D on C (i.e., report the regression equation).
Hint: The code to enter the vectors C and D into R is: C <-
c(3, 6, 8, 9, 1, 3) D <- c(2, 7, 5, 4, 0, 4)

Using the predict function in R, find each of the following
predicted values of D, for the given value of C regardless of
whether or not it is appropriate to do so. In real life you should
not calculate for predictions when it is not appropriate, but this
is just for practice.
Find when C = 6
Find when C = 4
Find when C =...
