Dilation rule can some one help me out plz

answer4 to the second power is 16

and 4 to the third power is 64,

if i put something wrong your not gonna like it so rather not say nothing.

the functions have the same rate of change i think. i narrowed it down to this answer and "the rate of change of tour 1 is greater" but i got it wrong using that answer so im assuming its the answer above. (this is a question i also answered from the iready site if anyone needs a reference)
