    Question Suppose that f and g are two functions..

    Suppose that f and g are two functions such that f(1)=2,f'(1)=-1,g(1)=-2 and g'(1)=3.Find the value of h'(1) for h defined below.

    a.h(x)=f(x).g(x)

    b.h(x)=(x^2 + 1). g(x)

    c.h(x)=f(x)/g(x)

    Simply differentiate h according to what you know and then substitute the required values of g,g',f,f',x. It would also help if you showed some of your work.
