The rate of change is 110 percent.
Yes they will be parallel. Now you try to solve it.
I’m having a hard time understanding your question
ANSWER
No, because there is no common ratio
EXPLANATION
The given sequence is
-1, 1, 4, 8
If this sequence is geometric, then there should be a common ratio among the consecutive terms.

Hence the sequence
-1, 1, 4, 8
is not a geometric sequence.
The P is 16x^2 -12 and Perimeter is the distance around the edge of a shape. So you divide your equation by 4 and the answer you get is 4x^2 - 3
