Which logarithmic graph can be used to approximate the value of y in the equation 4^y = 5?
The graph of function f of x equals negative log base 4 of x
The graph of function f of x equals negative log base 4 of x, plus 5
The graph of function f of x equals log base 4 of x, plus 5
The graph of function f of x equals log base 4 of x
[tex]4^{y} = 5
log_{4}(4)^{y} = log_{4}(5)
y=log_{4}(5)
So, the graph of the function should be y=log_{4}(x), or f(x)= log_{4}(x)
Correct answer is the last one.[/tex]
