PLS ANSWER QUICK W EXPLANATION

Answer 1

A

Explanation:

When you plug in each of the x, you get the right output.

2 x (4^1)= 8

2 x (4^2) = 2 x 16 =32

2 x (4^3)= 2 x 64= 128

2 x (4^4)= 2 x 256= 512

Answer 2

A

Explanation:

you multiply the previous term by 4 each time, so the base is 4.

That leaves A and B remaining.

If we substitute x = 1 into the two answers, A gives you 8 like in the problem while B gives you 4.

So the answer must be A
