If by D you mean y = (x+3)^2 , then yes
notice that since the y's are perfect squares, you know there had to be an x^2 somewhere, ruling out B and C
however, in A, the x value is off by 3 units, and the result of A would have been:
(4,16), (5,25), (6,36) ...
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 = x2
B. y = x + 15
C. y = 2(x+3)
D. y = (x + 3)2
is it D?
