Two separate bacteria populations grow each month and are represented by the functions f(x) = 3x and g(x) = 7x + 6. In what month is the f(x) population greater than the g(x) population?

    just a quick question are the equations 1. f(x) = 3x g(x) = 7x + 6 or 2. \[f(x) = 3^x ~~~g(x) = 7x + 6\]

    ok... that makes more sense... an easy method is to use a table of values |dw:1438027190144:dw| just keep going until f(x) is larger than g(x)
