If f(x)=x^2 and g(x)=5x-11, then what is fgg(x) when x=3?

g(3)=5(3)-11=15-11=4gg(3)=g(4)=5(4)-11= 20-11=9fgg(3)=f(9)=92=81fgg(3)=81

Solve the differential equation: dy/dx = tan^3(x)sec^2(x)


Consider the function f (x) = (2/3) x^3 + bx^2 + 2x + 3, where b is some undetermined coefficient: (a) find f'(x) and f''(x) and (b) if you know that f(x) has a stationary point at x = 2, use this information to find b.


Find the minimum value of the function, f(x) = x*exp(x)


find dy/dx of x^1/2 + 4/(x^1/2) + 4
