Do you understand it?

Should we call for backup?

First you would solve the equation $$6^y=x$$ take log on both sides $$log 6^y = log x$$ use the properties of exponents to change it to $$y~log 6 = log x$$ or $$\large y=\frac{log(x)}{log6}$$ Since the given equation has x=12, substitute x=12 in the above equation and solve for y. Use the point (12,y) to select the graph required.
