You cannot since the transformation is not a horizontal shift.

Piece wise functions can do everything. Take two pieces of two rational functions, one have a horizontal asymptote as x goes to -infinity and the other have a slanted (oblique) one as x goes to +infinity. It is still a rational function.

Yes it is. the two numbers will always have the same proportion to each other.

Yes, but x would be a function of y, not the other (usual) way round. The domain of the function would be y in (-infinity, +infinity) and the range x in [0, +infinity).

other horizontal lines? which would be 180 degrees i guess.

Well, if you solve the equation for "y", you have "y" as a function of "x". Or you can do it the other way round; solve for "x", to get "x" as a function of "y" (the first option is more commonly used, though).

A constant function is a function that always yields the same output value, regardless of the input. In other words, the function's output is a fixed value and does not depend on the input variable. Graphically, a constant function appears as a horizontal line.

If Y equals 2X - 2X - 24, then there is one root, and it is -24. The two 2X's cancel each other out.

Yes, y=x^2 is a non-linear function. In fact it is a parabola. Graphing one is quite easy using a table of values or other methods.

Just like the sine function displaced by pi/2. In other words the cosine equals 1 at 0 degrees, 0 at 90 degrees, -1 at 180 and so on.

No, horizontal lines are parallel to each other and parallel lines never intersect.

A horizontal line goes from left to right and looks like this. Also, all horizontal lines are parallel to each other. ______________________________________________________________________ ______________________________________________________________________

No, horizontal velocity does not affect the rate of vertical velocity. Each component of velocity (horizontal and vertical) is independent of the other. They act separately to determine the motion of an object.
