Let `f(x)=(sqrt2^x -2)/(sqrt2^x +2)` then if the graphs of `y=f(x)` and `y=f(4x)` are symmetrical about the points `(a_1,0)` and `(a_2,0)` respectively then `a_2/a_1=`

Let f(x)=(sqrt(2)^(x)-2)/(sqrt(2)^(x)+2) then if the graphs of y=f(x) and y=f(4x) are symmetrical about the points (a_(1),0) and (a_(2),0) respectively then (a_(2))/(a_(1))=

If the graph of the function y=f(x) is symmetrical about the line x=2, then

Let f(x)=sqrt(x^(4)+15), then the gragh of the function y=f(x) is symmetrical about

If f(x)=sqrt(1-sqrt(1-x^(2))) then at x=0

If f(x)=(sqrt(x)+(1)/(sqrt(x)))^(2)," then: "f'(2)=

Let k[f(x)+f(y)]=f(x sqrt(1-y^(2))+y sqrt(1-x^(2))) then k=:

If f'(x)=(1)/(-x+sqrt(x^(2)+1))andf(0)=(-(1+sqrt2))/(2) , then the value of f(5) will be
