Answer:
The graph of function f of x equals log base 3 of x.
Explanation:
We have the following equation:
3^y = 8
Taking logarithm(Logarithm with base equal 3) in both sides, we have:
lg_3 (3^y) = lg_3 (8)
ylg_3 (3) = lg_3 (8)
y = lg_3 (8)
So, you can approximate the value of y using the function f(x) = base 3 log (x). Just look for the value of that function for x = 8.
