Question

f(3x-4/3x+4) = x + 2

Find the equation of the tangent at the point (0, 10/3)

Answer 1

Please note that I can re-write your function as follows:
\[f(x) = \frac{2}{3}\frac{{x - 5}}{{x - 2}}\]

Answer 2

oops.. I have made an error:
\[f(x) = \frac{2}{3}\frac{{x - 5}}{{x - 1}}\]

Answer 3

Well, how did you reverse it to f(x) ?

Answer 4

please you have to change variable, so please solve this equation for x:
\[\frac{{3x - 4}}{{3x + 4}} = z\]
where z is the new variable

Answer 5

I see , thanks for your time.

Answer 6

thanks!
