If f(x) = |x+3|, then f'(3)=

(2) If f(x)=x+(1)/(x) , then [f(x)]^(3)-f(x^(3)) is equal to

If f: Rrarr R given by f(x) = (x^3) + 3, then f^-1(x) equals·:

Let f(x) be a continuous & differentiable function on R satisfying f(-x)=f(x)&f(3+x)=f(3-x)AA x in R . If f'(1)=-5 then f'(7) =

If f(x)=sqrt(x^(3)) , then f (3x) will be equal to

If f(x)=(1)/(3)x + 3 , then f^(-1)(x)=

If f(x)=4[x]-3|x| , find f(3.5) and f(-3.5).

If f_(1)(x) = 2x + 3, f_(2)(x) = 3x^(2) + 5, f_(3)(x) = x + cos x are defined from R rarr R , then f_(1), f_(2) and f_(3) are

If f(x) = | x | + [ x ] , then f( -3/2 ) + f( 3/2 ) is equal to : ( a ) 1 ( b ) -1/2 ( c ) 2 ( d ) 1/2

If f(x)=x+(1)/(x) , then prove that : {f(x)}^(3)=f(x^(3))+3*f((1)/(x))
