Why does the graph of a function never has two different points with the same x-coordinate?
That is simply a result of the definition of a function. A function is a mapping such that for each value of x there is only one value of y.
What is a zero of a quadratic function?
The "zero" or "root" of such a function - or of any other function - is the answer to the question: "What value must the variable 'x' have, to let the function have a value of zero?" Or any other variable, depending how the function is defined.
What can be useful when finding the value of a variable?
A value of some function of the variable at some point and an equation which links the two.
What is an extraneous solution of an equation?
when you solve a questiom, you get an answer. If you chect your answer by substituting the value of the variable in the question and you don't get L.H.S and R.H.S equal then your answer is called extraneous solution.
What is the output of a function a variable whose value depends on the input or independent variable?
the output variable is called the dependent variable. For example the function y = f(x) = 3x here x is independent and y is dependent; y changes when you change x
What is replacing a variable in an expression with a number value called?
Substituting.
How you can modify an integer variable value in a function?
with an assignment: variable = value variable += value variable /= -3; ...
To find the value of an algebraic expression by substituting a number for each variable and simplifying?
322
How do you solve simultanious equations?
By eliminating or substituting one of the variables in the two equations in order to find the value of the other variable. When this variable is found then substitute its value into the original equations in order to find the value of the other variable.
What is the output variable of a function?
It is a value in the co-domain [range] of the function.
How do you invoke function result () takes two float argument and returns an integer in c plus plus program?
You can do this by creating a forwarddeclaration of the function. You can call the forward drclared function inside the main to use it.int result(float num1, float num2);intmain(void){int value = result(3.14, 2.74);return (0);}intresult(float num1, float num2){int value = 0;// function codes goes here// you can alter the value of variable 'value'return (value);}The returning value of the 'result()' function is assigned to variable 'value' in 'main()'.
How is solving for a specified variable in a formula different to finding a solution for an equation or inequality?
With a formula, you know the variable's value, and you have to calculate the value of the function of it. With an equation, you know the function's value, and you have to calculate the value of the variable.
How is solving for a specified variable in a formula similar to finding a solution for an equation or inequality?
With a formula, you know the variable's value, and you have to calculate the value of the function of it. With an equation, you know the function's value, and you have to calculate the value of the variable.
Why does the graph of a function never has two different points with the same x-coordinate?
That is simply a result of the definition of a function. A function is a mapping such that for each value of x there is only one value of y.
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.
In mathematics what is a limiting value?
If the value of a function cannot be determined for any value of the independent variable, then, the value the function seems to be approaching would be its limiting value for that particular value of the independent variable.
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").
