Is this equation a function y equals 3squared plus 2x minus 3 is this a function?
You can tell if an equation is a function if for any x value that you put into the function, you get only one y value. The equation you asked about is the equation of a line. It is a function.
If a function is defined by an equation explain how to find its domain.?
The set of all values of x, for which the equation is true is the domain of the function defined by that equation.
What does express x as a function of y mean?
It means you should rearrange the equation so that x is on one side of the equal sign, and everything else on the other, with no "x" on the right side of the equation. For instance, if I was told to express x as a function of y and given the equation: x-4y=6 I would express x as a function of y by rearranging the equation to read: x = 6+4y
What is function notation in math terms?
An equation where the left is the function of the right. f(x)=x+3 is function notation. The answer is a function of what x is. f(g(x))= the answer the inside function substituted in the outside function.
Is the equation for a circle a function?
The equation for a circle is a function in that it can be graphed and charted. One common equation is x^2 + y^2 = r^2.
Rewrite the equation 2x 3y 6 as a function of x?
f (x) = 2/3 x + 2
How do you rewrite this equation so that y is a function of x 5y-2x equals 15?
It would be rewritten as y=(2/5)x+3
What steps would you take to write an equation in function form?
1) Solve the equation for the desired variable. 2) Write it in function notation. For example, if y = 2x + 3, it is already solved for "y"; just rewrite it as f(x) = 2x + 3.
Which equation is a function of x?
Any equation which maps each value of x in the domain to a value in the range is a function of x.
Rewrite the equation in function form -3x plus y equals 12?
y=3x+12
How would you rewrite x plus y equals -2 in a function form?
y = -x-2
What is the Log of 10 with base 100?
You can rewrite the equation as... 100=10x X=2
What is an example of a wrong function equation?
An example of a wrong function equation is f(x) = sqrt(x) for all non-negative x.
Rewrite the given equation in slope intercept form x plus y equals 8?
y=-x+8
Do a linear equation and a function share the same definition?
No. A function need not be linear. For example, y = sin(x) is a function of x but it is not a linear equation.
How do you rewrite this equation so that y is a function of x 1 plus 7y equals 5x-2?
1 + 7y = 5x - 2 7y = 5x - 3 - 5x = - 7y - 3 x = 7/5y + 3/5 ---------------------
How do you rewrite an equation in function form?
lets say you have to write 5x+6y=-12 in function form. when you are writing an equation in function form, you usually solve for f(x) or g(x), but in this case, y is the same as f(x) or g(x). so to write 5x+6y=-12 in function form, you do this: 5x+6y=-12 6y= -5x -12 subtract 5x from both sides y= -5/6x -2 divide both sides by 6
