1.Differentiate: x^2y^3+x = y I got 2x(y^3)+3y^3(x^2)+1=y ... Is that right? I think maybe I did it wrong.

2.The following function may be veiwed as a composite function f(g(x)). Find f(x) and g(x).

1

x^2+2x-3

is f(x)= to 1, and g(x)= to x^2+2x-3? that seems too simple.

3. With this one I'm preatty sure ou need to find the first derivitive, but I don't really know how to go about it.

Assume 4x^3+2xy-y^3=1/2. What is the slope of the graph at the point [1/2,-1]?

-any help would be greatly appreciated thanks.
