What is the domain and range of h of x equals absolute value of x plus 3?
domain is what x values you are allowed to put into an equation.In this case there is no restrictions. x= all real numbers.range is the output once you put these numbers in the equation.h(x)=>all real numbers > 0 because the absolute value can not be negative.
How do you know what the inputs and outputs are in functions?
if you have the equation, choose one of the pairs and put one of them in the position of x and solve. if you get the leftover value, the one you put in the equation is the x, independant variable, the other is y
What does x - y?
In expressions such as "x-y", both "x" and "y" can have any value. The value of "x-y" will depend on what the value of "x" and the value of "y" are.
What two numbers can you multiply to get -3?
Let one of the numbers be x and other be y. According to question: xy = -3 Put any value of x then value of y = -3/x. Let us say x = 1 then y = -3/1 = -3. And if x = 3 then y = -3/3 = -1. So for any value of x(except 0) we get a value of y. So there are infinitely many solutions of the given equation.
What number when you divide by 9 has a reminder 1?
There exists infinitely many solutions to the problem. Let the required number be x: By Euclid's Division Lemma we have x = 9q + 1(Since dividend is 9 and remainder is 1) Put any value of q(q must be natural number), say 5. On putting q = 5, we get x = 9*5 + 1 = 46. Put any value of q and you will get different value of x.
What does value of variables mean?
In algebra, variables are represented by letters such as x. A variable could be any number. That number is the "value" of the variable. In an expression, you can choose a number to put in for x, and simplify to get a number which is the value of the expression. In an equation, you can solve for the value of x, which will be the value of x which makes the equation true.

A value is in the domain of a function if there is a on the graph of the function at that x value?
i think you are missing the word point in the question, and if so, then yes. the domain of a function describes what you can put into it, and since your putting x values into the function, if there is a point that exists at a certain x value, then that x is included in the domain.
What is boxing in Java?
Boxing a value x is to put it in a class type rather than its primitive one. Ex. int x = 3; Integer Ix = x; // boxing x
Explain what do you mean by non-constant functions giving examples?
A constant function is one like f(x)=2 so no matter what value of x I put in, the output is 2. If I have f(x)=x, the identity, this is not constant. I put in 3 for example and get out 3, but if I put in 4 I get out 4. f(x)=x^2 is another non constant. I put in a number and the output is the number squared so this is NOT constant.

What is a squre number?
when you times the number by its value. for example if the number is 2. then to square it you would put 2 x 2. and for 8, it will be 8 x 8.
If x equals 3 What is the value of x?
the value of x is 3
What happens to the x-value of the ordered pair when the ordered pair is reflected over the x-value?
If the reflection is over the x value, the x-value does not change.
