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.

  1. 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
