If `G.C.F(25,15)=4x+1` then `x=`

(a) If f(x)=x+2 and g(x+1)=x+1 then find g@f(4)

Let g(x)=x^(3)-4x+6. If f'(x)=g(x) and f(1)=2, then what is f(x) equal to?

If: f(x)=5-x^2,g(x)=3x-4 , then: (f@g)(-1)=

If f(1) =g(1)=2 , then lim_(xrarr1) (f(1)g(x)-f(x)g(1)-f(1)+g(1))/(f(x)-g(x)) is equal to

If a,b are the zeroes of f(x)=x^(2)+3x+1 and c, d are the zero of g(x)=x^(2)+4x+1 then the value E=((a-c)(b-c)(a+a)(b+d))/(2) is

If f(x)=x^2 and g(x)=x^2+1 then: (f@g)(x)=(g@f)(x)=

If f(x),g(x) be twice differentiable functions on [0,2] satisfying f''(x)=g''(x)f'(1)=2g'(1)=4 and f(2)=3g(2)=9 then f(x)-g(x) at x=4 equals (A) 0 (B) 10 (C) 8 (D) 2

If g(x)=x^(2)+x+x-1 and g(f(x))=4x^(2)-10x+5 then find f((5)/(4))
