What is the symmetry to y-x3?
Let F(x,y) = y - x^3 Note that (-x)^3 = -(x^3) This suggests that F(-x,-y) = -F(x,y) (-x,-y) represents the point (x,y) reflected through the origin. You could say the function F has anti-point symmetry -- each point (x,y,F) is reflected through the origin at (-x, -y, -F).

What does f equal in algebra?
f(x) defines a function of x. You can consider it to be y.
What is the y -intercept of y equal 2x plus 3?
It is 3.

How do you complete the inverse of fx?
Follow this example. f(x) = (x+3)/5 To find its inverse, write y=f(x) y= (x+3)/5 Interchange x and y x = (y+3)/5 solve for y in terms of x 5x=y+3 y=5x-3 The inverse of f(x) is f^-1(x) = 5x-3

What is 3-y equal too?
That depends on the value of "y".
If x y=3 and y/x=2 then y is equal to?
1.5
What is fx for graphing mean?
f(x) is the same thing as y= example: f(x)=2x+3 OR y=2x+3
When you work with functions in algebra why is fx equal to y?
It actually is f(x) = y. F is a function, based on x, that gives you a result for y. An example might be f(x) = x2. This means that for every value of x, y has a value of x2.
If an inverse function undoes the work of the original function the original functions range becomes the inverse functions?
Maybe; the range of the original function is given, correct? If so, then calculate the range of the inverse function by using the original functions range in the original function. Those calculated extreme values are the range of the inverse function. Suppose: f(x) = x^3, with range of -3 to +3. f(-3) = -27 f(3) = 27. Let the inverse function of f(x) = g(y); therefore g(y) = y^(1/3). The range of f(y) is -27 to 27. If true, then f(x) = f(g(y)) = f(y^(1/3)) = (y^(1/3))^3 = y g(y) = g(f(x)) = g(x^3) = (x^3)^3 = x Try by substituting the ranges into the equations, if the proofs hold, then the answer is true for the function and the range that you are testing. Sometimes, however, it can be false. Look at a transcendental function.
