If `f(x)=x^100+x^99+x^98+........+1` then `f'(1)` is
`(a) 5050`
`(b) 5049`
`(c) 5051`
`(d) 50051`

If f(x)=1+x+x^(2)+.......+x^(100) then f'(1)=-

If f(x)=x^(100)+x^(99)++x+1, then f'(1) is equal to 5050 b.5049 c.5051 d.50051

If f(x)=x^(100)+x^(99)+……+x+1 , then f(1) is equal to

If int(dx)/((x+100)sqrt(x+99))=f(x)+C , then f(x) is

f(x)=x^(2)-2ax+a(a+1),f:[a,oo)rarr[a,oo) If one of the solution of the equation f(x)=f^(-1)(x) is 5049, then the other may be 5051 (b) 5048 (c) 5052 (d) 5050

If f(x)=1-x^(2)-x^(3)+-x^(99)+x^(100) then f'(1) equals 150 b.-50 c.-150 d.50

If f(x)=prod_(n=1)^(100)(x-n)^(n(101-n)), where prod_(i=1)^(k)a_(i) stands for product a_(1)dot a_(2).........a_(k), then (f(101))/(f'(101))=(a)5050( b) (1)/(5050) (c) 10010 (d) (1)/(10010)

If x!=1\ a n d\ f(x)=(x+1)/(x-1) is a real function, then f(f(f(2))) is (a) 1 (b) 2 (c) 3 (d) 4

if f(x)=3|x|+|x-2| then f'(1) is equal to a)2 b)1 c)3 d)0

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
