Question

The ordered pairs (1, 1) , (2, 16) , (3, 81) , (4, 256) , and ( 5, 625) represent a function. What is a rule that represents this function?
A) y = 4^x
B) y = 4x
C) y = x^4
D) y = x + 4

Answer 1

Answer:

c

Step-by-step explanation:

Answer 2

Answer:

C

Step-by-step explanation:

Note that each of the y- coordinates is the x- coordinate raised to the power of 4.

(1, 1) → y = $1^{4}$ = 1

(2, 16) → y = $2^{4}$ = 16

(3, 81) → y = $3^{4}$ = 81

(4, 256) → y = $4^{4}$ = 256

(5, 625) → y = $5^{4}$ = 625

Thus the rule is y = $x^{4}$ → C
