8. The ordered pairs (1, 2), (2, 4), (3, 8), (4, 16), and (5,32) represent a function. What is a rule that represents this function?

a. y= x^2
b. y= 2x
c.y= 2^x
d. y= x+2

Answer 1

it is C.

Answer 2

Because y=2^(1)=2 Thus the point (1,2)
y=2^2=4 thus (2,4)
y=2^3=8 thus (3,8)
y=2^4=16 thus (4,16)
y=2^5=32 thus (5,32)
