Question

Which graph represents the function f(x)=log(3x−1)?

Answer 1

Case: Logarithmic graph

Method:

To plot the graph:

f(0)= log [3(0)-1]

f(0)= undefined

`\begin{gathered} f((2)/(3))=log[3((2)/(3))-1] \\ f((2)/(3))=log(2-1) \\ f((2)/(3))=log1 \\ f((2)/(3))=0 \end{gathered}`

The graph, therefore:
