Answer:
(√1 + 5x^2) / x + 1
Step-by-step explanation:
f(x) = (√x^2 + 5 ) / x + 1
Replacing 1/x in place of x
f(1/x) = (√1/x^2 + 5) / 1/x + 1
= (√1/x^2 + 5)/ (1/x + 1)
Taking LCM,
(√1 + 5x^2) / √x^2 ÷ (1 + x )/x
= (√1 + 5x^2 )/ x ÷ x + 1 / x
= (√1 + 5x^2) / (x + 1)..... ( cancelling both the x )
Hence, f(1/x) = (√1 + 5x^2 ) / (x + 1)
