Question

WILL GIVE MEDAL!!!

Given the following information, determine the explicit equation for the geometric sequence.

f(1) = 8, common ratio, r = 2

Give your answer starting with f(x)=. Use x as the variable. Do not include spaces. If an exponent is needed, use the ^. For example, x^2 would be written x^2. Use parantheses if needed to include multiple parts as an exponent. For example, 3^{(x+1)} typed as 3^(x+1) shows an exponent of x+1. Use either a * or place the second item in () to show multiplication.

Example answer: f(x)=3(2)^x

Answer 1

I got f(x)=8(2)^x is this correct?

Answer 2

not quite

Answer 3

for \[f(x)=8\times 2^x\] you would have \(f(1)=16\)

Answer 4

Oh, so what do I do?

Answer 5

use 4 instead of 8

Answer 6

Okay thank you!
