The function f(x) = 6x is an exponential function where the base is 6. In general, the growth factor of an exponential function of the form f(x) = a * b^x, where ‘a’ is a constant and ‘b’ is the base, indicates how much the function grows for each unit increase in x.
In this case, since the function is given as f(x) = 6^x, the growth factor is represented by the base of the exponent, which is 6. This means that for every unit increase in x, the output of the function will be multiplied by 6.
To summarize, the growth factor of the function f(x) = 6^x is 6.
