If f(x)=e^(sqrt(2x+3)), find f'(11)

If f(x)=(x-4)/(2sqrt(x)), then f'(4) is equal to

If f(x)=x^(3)+7x^(2)+8x-9, find f 4)

Find the domain of the function: F(x)=(sqrt(9-x^(2)))/(sqrt(x^(2)-4))

If the function f(x) defined as : f(x)=(x^(4)-64x)/(sqrt(x^(2)+9)-5), for x!=4 and =3, for x=4 show that f(x) has a removable discontinuity at x=4

If f(x)=x^(2) + 5x-3 , then evaluate f(4)

Find the domain of each of the following real valued functions of real variable: f(x)=sqrt(x-2) (ii) f(x)=(1)/(sqrt(x^(2)-1)) (iii) f(x)=sqrt(9-x^(2))( iv )f(x)=sqrt((x-2)/(3-x))

If f(x) is continuous at x=4 , where f(x)=(x^(4)-64x)/(sqrt(x^(2)+9)-5) , for x!=4 , then f(4)=
