Question

The ordered pairs (1, 81), (2, 100), (3, 121), (4, 144), and (5, 169) represent a function. What is a rule that represents this function?

A) y=x^8
B) y=8^x
C) y=(x+8)^2
D) y=8x

Answer 1

C) y=(x+8)^2

Notice that 81, 100, 121, 144, and 169 are all perfect squares but not the x value with which they are paired.
