If `f(x)=(x-4)/(2sqrt(x))`,then `f'(1)` is : (a) `5/4` (b) `4/5` (c) 1 (d) 0

If f(x) =(x-4)/(2sqrt(x)) , then f^(')(1) is equal to

If f(x)=(x-4)/(2sqrt(x)),backslash then f'(1) is (5)/(4) b.(4)/(5) c.1 d.0

f(x)=sqrt(x-4-2sqrt(x-5))

1.If f(x)=((x^(2)-4)/(x-2)) ,then f(2) is (a) 0 (b) 2 (c) 4

If "x=sqrt(5)+2",then "x-(1)/(x)" equals: (a) "4," (b) "3," (c) "2," (d) "1"

if f(x)=sqrt(x+2sqrt(2x-4))+sqrt(x-2sqrt(2x-4)) then f'(3)+f'(6)= (A) 0 (B) 1 (C) 2 (D) 1/2

If 2f(x)-3f((1)/(x))=x^(2)(x!=0), then f(2) is equal to (a)-(7)/(4)(b)(5)/(2)(c)-1 (d) none of these

If x=5+2sqrt(6), then sqrt((x)/(2))-(1)/(sqrt(2x))= (a) 1 (b) 2 (c) 3 (d) 4

The domain of f(x)=(x-5)/(x-4)+sqrt(x-4) is

Let f: RvecR be a continuous and differentiable function such that (f(x^2+1))^(sqrt(x))=5forAAx in (0,oo), then the value of (f((16+y^2)/(y^2)))^(4/(sqrt(y)))fore a c hy in (0,oo) is equal to 5 (b) 25 (c) 125 (d) 625
