If g:[−2,2]→R, where f(x)=x3+tanx+x2+1P is an odd function, then the value of parametric P, where [.]denotes the greatest integer function, is
−5<P<5
P<5
P>5
None of these
g(x)=x3+tanx+x2+1P or g(−x)=(−x)3+tan(−x)+(−x)2+1P =−x3−tanx+x2+1P
Now, g(x)+g(−x)=0 Because g(x) is a odd function,
x3+tanx+x2+1P+−x3−tanx+x2+1P=0 or 2x2+1P=0 or 0≤x2+1P<1 Now, x∈[−2,2]∴ 0≤5P<1 or P>5
