The logarithmic graph that can be used to approximate the value of Y in the equation 6^y = 12 is as shown in the attached figure.
It can be obtained easily by replacing the number 12 with x which will give us the function 6^y = x, then graphing the function.
To find the solution of 6^y = 12, just intersect the graph with the line x=12
which will give us the solution of 6^y = 12 which will equal 1.387
