How do you find the x value of an equation if you are only given the value of y using function notation?

You use the inverse function (if one exists).
So, if y = f(x) then x = f-1(y)

To solve the system given below using substitution it is best to start by solving the second equation for y?
True
What term is used to describe when two functions are linked together by using output of the first function as input of second function?
function composition
In the equation y equals 2x2 - 5x - 18 which is a value of x when y equals 0?
x = 9/2 or x = -2 Solved by using the quadratic equation formula.
How do you solve the equation by using the zero element?
Not sure what you mean by "zero element". If an expression is equal to zero, and you can factor it, then at least one of the factors must be zero; this is often useful to solve an equation.
What is the vertex of a parabola whose equation is y equals x 32?
The given equation is not that of a parabola since there are no powers of 2. Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "equals" etc. And using ^ to indicate powers (eg x-squared = x^2).
How do you write an equation using function notation?
let's take an arbitrary equation, or maybe two or three so you can see how to do it. y=2x+6 t=z^2+3z w=r^4+pi Ok, the first equation, you pick the x and put it in the equation and multiply it by 2 then add 6. If you do all this you get y. So y is really a function of x or function of x is written f(x) is the way we say this So to write the equation in function notation we write f(x)=2x+6 Same thing for the second equation z is what we put in. It is the independent variable. So t is just a function of z we write f(z)=z^2+3z Last equation is the same f(r)=r^4+pi
How to solve a f x equation?
I guess you mean an equation written in function notation, for example: f(x) = 3x + 2 For the purposes of doing math, it may help to think of this as an alternative way of writing, for example (using the function above): y = 3x + 2 It isn't clear from the question what you want to "solve", but if you write the equation this way, it might become a bit less confusing.
How do you rewrite as a function of x using function notation for 2x plus 3y equals 4?
If 2x + 3y = 4, y= (4 - 2x)/3. In function notation, f(x) = (4 - 2x)/3.
If w stands for width the input value and H w stands for height the output value rewrite the equation above using function notation Use the slash to indicate a fraction?
h(w)=100/w
How do you find for the zero of a linear function?
If it is a linear function, it is quite easy to solve the equation explicitly, using standard methods of equation-solving. For example, if you have "y" as a function of "x", you would have to solve the variable for "x".
Without using a graph how can you tell if an equation is a function or relation?
Verticle line test man. If it intersects two points it is its not a function. if it hits one point it is a function. and im currently looking up to see how it is a equation...

An expression in which symbols and formulae represent a chemical reaction?
A stoichiometric equation is a notation that describes a chemical reaction using chemical formulae. An example is CH4 + 2 O2 -> CO2 + 2 H2O
How do you get the dimensions of rectangular lot given the perimeter and area?
By halving its perimeter and using the quadratic equation formula.
