x ∈ R दिया है इसलिए वास्तविक समूच्य है ।

f (x) =  में f(2) और f(\(\frac{1}2\)) का मूल्य ज्ञात करेंगे ।

x = 2 के लिए f(2) =

 

अब f(2). f (\(\frac{1}2\)) ज्ञात करने के लिए f(2) = \(\frac{7}{12}\) और f(\(\frac{1}2\)) – 89 रखने पर f(2). f(\(\frac{1}2\))

\(\frac{7}{12} × \frac{8}9 = \frac{506}{108}\)

∴ = \(\frac{14}{27}\)
