Question

if 3f(x)+4f(1/x)=1/x-3 for all non zero x then f(x)=​

Answer 1

Answer:

3f(x) + 5f(1/x) = 1/x-3 ...eqn. 1 Replacing x by 1/x; 3f( 1 x 1x) + 5f(x) = x - 3...eqn. 2 Multiply eqn. 1 by 3 and eqn. 2 by 5, and then subtract them Read more on Sarthaks.com - https://www.sarthaks.com/1102422/if-3f-x-5f-1-x-1-x-3-for-all-non-zero-x-then-f-x
