We simply substitute the values of x and check if the values of y match.
y(1) = 19,000
y(2) = 18,050
y(3) = 17,148
y(4) = 16,290

As is visible from the table, the first value quoted is incorrect.

One has a place value of 10 times the other. Like in the number 22, one 2 stands for 20, which is 10*2.
