Choice D is true. It is just another way to write the given function.

To confirm choices A through C, replace x as follows and do the math:

For A, let x = -3. Does it really yield -11?

For B, let x = 0. Does it really yield 5?

For C, let x = 1/2. Does it really yield 4?

So given sequence is a geometric sequence where terms increase or decrease by a constant common ratio(r)

Formula to find terms in Geometric sequence is " ar^n-1 where a is first term , r is common ratio and n is number of items

In this case , first term (a) is 1 , common ratio(r) is succeeding term/preceding term = 4/1 = 4 and number of items be (n).

Applying "ar^n-1 " we get,

1*4^n-1 which is , 4^n-1

Thats the formula which represents the situation....
