" If "f(x)=x sqrt(ax-x^(2))" (for "a>0" ) then "

Let f(x) = x sqrt(4ax - x^(2)), (a gt 0) . Then f(x) is a)increasing in (0, 3a), decreasing in (3a, 4a) b)increasing in (a, 4a), decreasing in (5a, oo) c)increasing in (0, 4a) d)None of these

Find the interval in which f(x)=x sqrt(4ax-x^(2)),(a<0) is decreasing

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

If f(x)=sqrt(ax)+(a^2)/(sqrt(ax)) , then f^ (a)=

If f(x)=sqrt(ax)+(a^2)/(sqrt(ax)) , then f^ (a)=

If f(x)=(sin^(2)ax)/(x^(2))" for "x ne 0, f(0)=1 is continuous at x=0 then a=

If f(x) is continuous at x=a, where f(x) = (sqrt(x)-sqrt(a) + sqrt(x-a))/sqrt(x^(2) -a^(2)) , for x ne a , then f(a)=
