You cannot undefine a member function.
If you are asking about member functions. When we declare a function inside a class then that function becomes member function of that class and this function can access the whole class
A normal function is any function that is not a member of any class. Normal functions that operate upon a class are referred to as non-member functions, however a non-member function can also be a member of another class. Any class may declare any non-member function to be a friend of the class, in which case the function becomes a friend function.A member function is a member of a class and may be declared static or non-static. Non-static member functions have the following 3 properties:Private access to the class members.Scoped to the class.Must be invoked against an object of the class (has a 'this' pointer).Static member functions have the first two properties only while friend functions have the first property only. Non-member functions that are not friends of the class have none of these properties.
Yes. Any function can be overloaded. However you cannot override a static member function. Only instance members can be overridden.
Static member functions, member function templates and constructors cannot be virtual.
Nothing stops a member function from changing any of the values in a class. By convention, an accessor function is used to give read only access to class data, but that does not mean that it is prohibited from doing so. It is a member function, after all, and it has all the rights of any member function of the class.
Undefined.
Undefined
A rational function can be undefined at particular values of ( x ) when the denominator equals zero, as division by zero is undefined in mathematics. This typically occurs at specific values of ( x ) that make the denominator a zero polynomial. Identifying these values is essential for understanding the function's domain and any potential discontinuities.
An undefined graph typically occurs when there is a division by zero in a mathematical equation, resulting in an infinite or undefined value. In a graph, this would manifest as a vertical line or asymptote where the function approaches infinity or negative infinity. This can happen, for example, when plotting the graph of a rational function where the denominator equals zero at a certain point.
Undefined; large
Yes, a vertical asymptote represents a value of the independent variable (usually (x)) where a function approaches infinity or negative infinity, and the function is indeed undefined at that point. This is because the function does not have a finite value as it approaches the asymptote. Thus, the vertical asymptote indicates a discontinuity in the function, where it cannot take on a specific value.

Yes and the straight line could be parallel to the x or y axes
This is not a function. To be a function, there must be a one to one relationship between the independent variable (usually represented by the horizontal or x axis) and the dependent variable (usually represented by the vertical or y axis). A line with undefined slope is a vertical line, so there are an infinite number of possibilities for y and only one possible value of x, so this is not a function.
Mathematical operations involving undefined are not permitted. So the answer is undefined.
No, it would have to be parallel to the y-axis, making the slope undefined and having only a single x-value. Not a linear function.
x is a member of the function's domain, y is a member of the function's range.
