A function is a rule that assigns each value of the variable to exactly one value of the dependent variable?
I found two answers for this question. A function is a rule that assigns to each value of one variable (called the independent variable) exactly one value of another variable (called the dependent variable.) A function is a rule that assigns to each input value a unique output value.
What else can I help you with?
Specifying exactly what is to be measured in assigning a value to a variable is called what?
operationalization
A relation with exactly one output for each input?
It's a type of function
Write a program to return a function using class in C Plus Plus?
Classes cannot return values, only functions can return values. But you cannot return a function from a function, you can only return a function pointer -- a pointer variable holding the address of the function you wish to return. All possible return values must be of the same type, therefore all function signatures and return types must be exactly the same -- only the name of the functions can differ.
Why pointer variable size of is 4bytes in 32 bit compiler?
Because 32 bit is exactly four bytes.
How do you update a data file in c plus plus with a reference?
You cannot store references. A reference is nothing more than an alias, an alternate name for an existing variable or constant. References are primarily used when passing variables to functions such that the function can operate upon the variable itself -- known as passing by reference. The function refers to the variable by a different name, an alias, but it is the same variable. By contrast, when passing a variable by value the function uses a copy of that variable, assigning the variable's value to that copy. References are often confused with pointers, primarily because C uses the term to mean a pointer (hence the term, dereferencing). But in C++ a reference is a separate entity altogether. Unlike a reference, a pointer is a variable in its own right, one that can be used to store a memory address. Since a pointer has storage, you can store a pointer in a data file. However, in reality you are only storing the pointer's value -- a memory address -- not an actual pointer. Pointers and references are similar insofar as they can both refer to an object. A pointer does this by storing the memory address of the object, while a reference refers directly to the object itself. Thus if you have a pointer and a reference to the same object, the pointer's value is exactly the same as the address of the reference. Therefore the only way you can store a reference is by storing the object being referred to, not the reference itself.
A function is a rule that assigns each value of the independent variable to exactly value of the dependent variable?
false
What rule assigns each value of the independent variable to exactly one value of the dependent variable?
It is any invertible function.
A is a rule that assigns each value of the independent variable to exactly one value of the dependent variable?
This will be a math function. Each choice is only going to have one answer in this kind of function.
When can we say that a function is a relation?
When it doesn't fulfill the requirements of a function. A function must have EXACTLY ONE value of one of the variables (the "dependent variable") for every value of the other variable or variables (the "independent variable").
When can we say that a relation is a function?
When it doesn't fulfill the requirements of a function. A function must have EXACTLY ONE value of one of the variables (the "dependent variable") for every value of the other variable or variables (the "independent variable").
A function is a relatship that assigns one?
It assigns exactly one output value for each input value.
When can we say that a relation is not a function?
When it doesn't fulfill the requirements of a function. A function must have EXACTLY ONE value of one of the variables (the "dependent variable") for every value of the other variable or variables (the "independent variable").
What is it called exactly what you are going to measure?
A dependent variable.
What is a rule that assigns exactly one output value to each input value?
A function is a rule which assigns exactly one output f(x) to every input x.
What is the relation that assigns exactly one output value to one input value?
It is a bijective function.
Is dependent variable the variable that can't change?
Not exactly sure what you mean by "can't change." However, I if I do understand you correctly, the dependent variable CAN change. The dependent variable will change according to the independent variable's value and overall effect. For example, in an experiment involving water's effect on plants, the dependent variable may be the height of the plant or the glucose produced. Based on the amount of the independent variable (represented on the x axis of a data graph), the dependent variable will increase or decrease. In this case, both dependent values (glucose and height) would probably increase.
What is a A relationship that assigns exactly one output value to one input value?
It is a injective relationship. However, it need not be surjective and so will not be bijective. It will, therefore, not define an invertible function.
