How to solve a log function
WebIf you meant: f (x) = log₃ [ (4x-3)²] Then the domain is x≠ ¾ because that value would lead to a log of 0. The square makes sure we never get a negative value for the argument. If you mean f (x) = {log₃ [ (4x-3)}² which is usually written as log²₃ (4x-3) then: As before x≠ ¾ due to being a log of 0. WebApr 30, 2024 · To graph the function, we will first rewrite the logarithmic equation, y = log2(x), in exponential form, 2y = x. We will use point plotting to graph the function. It will be easier to start with values of y and then get x. Try It 4.4.1 (a) Graph: y = log3(x). Answer (a) (b) Graph: y = log5(x). Answer (b)
