Which logarithmic graph can be used to approximate the value of y in the equation 3y = 4?

**Answer 1**

Perhaps you mean 3^y = 4

Take logarithms base 10 of both sides:

log(3^y) = log(4)

But log(3^y) = y*log(3)

y = log(4)/log(3) = 1.261859

Thus 3^1.261859 = 4

Could have used natural logs

Ln(3^y) = yLn(3) = Ln(4) —–> y = Ln(4)/Ln(3) = 1.261859

**Answer 2**

No logs needed

y = 3/4
