So one problem is f(x)=x^3 , In my head I know its x^(1/3) because
Then i think I Do the third square root to both sides to get that answer but am not sure.
This is the one where Im haveing the most trouble
f(x)=(3x+1)/(2x-5) So I Multipy each side by 2x-5 and get
y(2x-5) which factors into
2xy-5y=3x+1 and am not sure what to do from here
Any help would be greatly appreciated.
The answer in the back of the book is y=(5x+1)/(2x-3)
even with that I cant figure out how they came up with it
