y is a function of x if
- for each value of x (in the domain) there is a value of y, and
- for each value of y (in the range) there is at most one value of x.

Is y equals x-3 a function?
y = x - 3 is a linear function where for each x-value we find one and only one y-value.
Find the function whose inverse is the same as the function itself?
f ( x ) = (x-2)/(x-1)if y = (x-2)/(x-1)yx-y= x - 2yx-x= -2+yx(y-1)=y-2x = (y-2)/(y-1)so g ( x ) the inverse function is also (x-2)/(x-1)
What is the function of a ratio?
The function is f(x, y) = x/y where x, y are real, and y ≠0
How do you make y a function of x?
You have Y and you have X. F=function. Y is already a function of X because here's another way you write Y: F(X). So instead of putting Y you out F(X) which meanf "F or X" or "function of X".
What is the inverse function of y equals 2x minus 4?
To find the inverse of a function, you replace x with y and y with x. Here, y=2x-4 would become x=2y-4. Now, we solve for y. 2y=x+4. y=(x/2)+4, and that is the inverse equation.
How do you find the y-intercept of a function?
The y-intercept is the value of a function f when x is equal to zero. So, substitute 0 for x into the equation and find the value of y.
Is y equals x-3 a function?
y = x - 3 is a linear function where for each x-value we find one and only one y-value.
Find the coordinates of a second point on the graph of a function f if the given point is on the graph and the function is even?
If the point (x,y) is on the graph of the even function y = f(x) then so is (-x,y)
How do you find the period of tangent function?
You find the smallest positive value y such that tan(x + y) = tan(x) for all x.
Find the function whose inverse is the same as the function itself?
f ( x ) = (x-2)/(x-1)if y = (x-2)/(x-1)yx-y= x - 2yx-x= -2+yx(y-1)=y-2x = (y-2)/(y-1)so g ( x ) the inverse function is also (x-2)/(x-1)
How do you find the numbers x-intercepts of function y equals 5x'2?
5x²=0 X=0 the function y=5x² only intercepts x when x = 0
What is the function of a ratio?
The function is f(x, y) = x/y where x, y are real, and y ≠0
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)
Is x equals y a function?
y = x This is a line and a function. Function values are y values.
How do you make y a function of x?
You have Y and you have X. F=function. Y is already a function of X because here's another way you write Y: F(X). So instead of putting Y you out F(X) which meanf "F or X" or "function of X".
What is a binary function?
A binary function is a function f if there exists sets X, Y, and Z, such that f:X x Y -> Z where X x Y is the cartesian product of X and Y.
What is the inverse function of y equals 2x minus 4?
To find the inverse of a function, you replace x with y and y with x. Here, y=2x-4 would become x=2y-4. Now, we solve for y. 2y=x+4. y=(x/2)+4, and that is the inverse equation.
