(b) क्या x=a पर फलन `f(x) = 1/(x-a)` सतत है?

फलन f(x) पर अवकलनीयता

If (x/a) + (y/b) = 3 and (x/b)-(y/a) = 9, then what is the value of x/y? यदि (x/a) + (y/b) = 3 तथा (x/b)-(y/a) = 9 है, तो x/y का मान क्या है? ,

From mean value theorem, f(b)-f(a) = (b-a)f^(1)(x_(1)), a lt x_(1) lt b if f(x) = ( 1)/( x) then x_(1) =

{:(1.if F (X) = (1)/(x) then f'(1) =A, 2.If f (x) = (x+1)/(x+3) then f '(-1) =B),(3.If f(x)=x^(2)then f'(1)=C,4. If f(x)=logx then f'(3)=D):} The ascending order of A,B,C ,D is

If f(x)=(x-1)/(x+1), then f(f(ax)) in terms of f(x) is equal to (a) (f(x)-1)/(a(f(x)-1)) (b) (f(x)+1)/(a(f(x)-1))(c)(f(x)-1)/(a(f(x)+1))(d)(f(x)+1)/(a(f(x)+1))

If f((ax+b)/(x-a))=x, then f^(-1)(x)= (a) x (b) (bx+a)/(x-b)( c) f(x)

Suppose f(x) =[a+b x , x 1] and lim f(x) where x tends to 1 f(x) = f(1) then value of a and b?

If x^2- 12x+33 = 0 , then what is the value of (x- 4)^2 + [1//(x-4)^2] ? यदि x^2- 12x+33 = 0 है, तो (x- 4)^2 + [1//(x-4)^2] का मान क्या है?
