For the x-values 1,2,3, and so on, the y-values of a function form a geometric sequence that increases in value. what type of function is it? a.)increasing linear b.)exponential decay c.)exponential growth d.)decreasing linear ( need answer asap)

C) Exponential Growth

Step-by-step explanation:

The geometric sequence is of the form a(n) = a*r^(n-1). For example, a(n) = 2*3^(n-1) with a = 2 as the starting term and r = 3 as the common ratio.

The variable n is in the exponent. We can replace it with x to get y = 2*3^(x-1); which graphs out to an exponential curve going uphill as you read it from left to right. This shows exponential growth, which matches with the growth of the original geometric sequence.

The correct answer would be decreasing linear (D)
