Question

integral of (dx)/(4-9x)

I got -(1/9)*log(4-9x)+C

But, my homework program keeps saying it's wrong... someone help?

Answer 1

your homework program is mistaken
stick to your answer

Answer 2

maybe it is a syntax problem
maybe i wants \(\ln(4-9x)\) rather than \(\log(4-9x)\)

It says evaluate the indefinite integral
