Question

Which logarithmic graph can be used to approximate the value of y in the equation 4^y = 5?

Answer 1

Turn 4^y = 54

y

=5 into a logarithm and that is the graph

4^y = 54

y

=5 = log_4 x =ylog

4

x=y

log_4 x =ylog

4

x=y

OR

y = log_4 xy=log

4

x

The graph of y = log_4 xy=log

4

x can be used.
