1.	Let f(x)=2tan−1x and g(x)=x+2. Then the number of integer(s) satisfying ((f∘g)(x))2−5(f∘g)(x)+4>0 where x∈(−10,10) is
Answer» Let $f (x) = 2 {tan}^{- 1} x$ and $g (x) = x + 2.$ Then the number of integer(s) satisfying $((f \circ g) (x))^{2} - 5 (f \circ g) (x) + 4 > 0$ where $x \in (- 10, 10)$ is
