I need help converting this exponential equation "4^y=8" to a logarithmic equation so I can graph it.

I know 4 is the base, y is the exponent and 8 is the argument.

So the log expression is "log subscript 4 eight=y" right? My question now is, how do I graph it?

log both sides then remember that

$$\log(a^b) = a \log(b)$$

log(4^y)= 4 log y? or is it supposed to be |dw:1385513889051:dw|?
