Pull back the constant and remember what the derivative of natural log. is.
my book says: f(x)=1/x ---> F(x)=ln(x) But I don't see what happens to 1 and 10 in my case
As I said, you can just pull out that constant, it's a property. It says
Oh, so my answer is just F(x)=ln(x)+k ???
No If F(x)=ln(x)+k then f(x)=1/x Answer is simply F(x)=10 lnx + k
