Answer 2

according to the problem it should be attempted by the ratio test

Answer 3

the x value won't change since y = 5 is a line parallel to the x-axis...

the point is 2 units about the line... so y' is 2 units below the line....

Hence the coordinates of A' is (2, 1)

Answer 4

The ratio test and the root test are two different things:
