The ordered pairs (1,2),(2,4),(3,8),(4,16), and (5,32) represent a function?
a. y=x^2
b. y=2x
c. y=2^x
d. y=x+2******

The ordered pairs (1,16),(2,25),(3,36),(4,49), and (5,64) represent a function. What is a rule that represents this function?
a. y=x^2
b. y=x+15
c. y=2(x+3)***
d. y=(x+3)^2

1. first one: y = 2^x

why did you possible pick c)
not a single one of the pairs given satisfies that equation.
It is clearly y = (x+3)^2 , that is, d)
