**PLS HELP PLEASE** A geometric sequence has 32 as its first time and 1/2 as its fourth term. which of the following functions correctly expresses this relationship in terms of the nth term

a. f(n)=32+1/2(n-1)

b. f(n)=32+1/4(n-1)

c. f(n)÷32•1/2^(n-1)

d. f(n)=32•1/4(n-1)
​

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
