Which functions graph is a translation of the graph of f(x)=x shifted 5 units to the right a. g(x)=5x
b. g(x)=x-5
c. g(x)=x+5
d. g(x)=-5x

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:
