If `y=f(x)=3x^2+2x+4`, then value of y at `x=f(2)` will be

1.If y=sin x, then (d^(2)y)/(dx^(2)) will be 2. If y=f(x)=3x^(2)+2x+4, then value ofy' at x=f(2) will be:

If y=f(x^(2)) and f'(x)=sqrt(3x^(2)+1) then the value of (dy)/(dx) at x=2 is -

If y = f(x) and y^(4) - 4y + x = 0 . If f (-8) = 2 , then the value of |28 f' (- 8)| is

If y = f(x) and y^(4) - 4y + x = 0 . If f (-8) = 2 , then the value of |28 f' (- 8)| is

If y=f(x)=(2x-1)/(x-2), then f(y)=

If y=f(x)=(3x-5)/(2x-m)and f(y)=x, find the value of m.

If 2f(x+y)=f(x).f(y) for all real x, y. where f'(0)=3 and f(4)=25 , then the value of f'(4) is equal to

If f(2x + 3y, 2x-3y)=4xy , then find the value of f(x,y)

If f(2(x)/(y))=f(2x)-f(y) for all x,y>0 and f(3)=2, then the value of [f(7)], is

If f(x) = (a^x + a^-x)/2, (a gt 2) then the value of f(x + y)+f(x - y) is equal to
