Question 452085
Find the domain of the logarithmic function. 
f(x) = ln (4x - x^2)  
The natural log function is only defined for positive values of the argument.
The limiting values of x are obtained by factoring the expression and seting = 0:
x(4-x) = 0
This gives x = 0 , x = 4
So the domain is 0 < x < 4.
Ans. A
The graph is below:
{{{graph(300,300,-6,6,-10,10,ln(4x-x^2))}}}
