Implicit: x2 + 2y = 5 Explicit : y = (5 - x2)/2
An explicit function ("y" as a function of "x") is one of the form y = ..., where only a single "y" appears on the left, and no "y" appears on the right. Therefore, the function you give is implicit.An explicit function ("y" as a function of "x") is one of the form y = ..., where only a single "y" appears on the left, and no "y" appears on the right.

I understand this to be y3. Then the derivative is 3y2. If y is considered a so-called 'implicit function' of x then the derivative might be written 3y2 dy/dx.
The problem is If y³−3y+4x=0, find y′ by implicit differentiation
As the name suggests, a conversion function is a function that converts a value from one type to another. Many such conversions are either implicit or built-in operations, such as when converting from an int to a double. However, when converting between user-defined types, or between a user-defined type and a built-in type, we must write a function to explicitly perform the conversion for us. In object-oriented languages, we rely on conversion constructors and conversion operators to perform these conversions implicitly, but in C we must explicitly call the appropriate conversion functions.
