Consider the functions f(x) = logb(x) and g(x) = a · logb(x). No matter the base, when a positive value is substituted for a as compared to the parent function f(x), and a > 1, the graph of g(x) results in a . No matter the base, when a positive value is substituted for a as compared to the parent function f(x), and 0 < a < 1, the graph of g(x) results in a . No matter the base, when a negative value is substituted for a as compared to the parent function f(x), the graph of g(x) results in a .
