Which of the following functions represents a geometric sequence? Why?
Answer Choices
The function f(x)=x7 represents a geometric sequence because each term is raised to the seventh power to make it greater.
The function f(x)=7x represents a geometric sequence because each term is the next higher multiple of 7.
The function f(x)=7x represents a geometric sequence because each term is 7 times as great as the previous term.
The function f(x)=−7x+3 represents a geometric sequence because each term is 7 less than the previous term.

check the ratio between terms. If it is constant, you have a GP.
For example, check the first 3 terms of
f(x) = 7x+3
f(1) = 4
f(2) = 11
f(3) = 18
(11)/(4) ≠ (18)/(11) so not a GP
Use ^ for exponents, as in
x^7 and 7^x
