The translation is vertical if the added term is outside the main function and horizontal if it is inside it, next to the x.

For example, y = x^2 represents a parabola, with its lowest point at (0,0). If we have the equation y = x^2 + 2 then we have translated the parabola up two units -- its lowest point is now x = 0, y = 2. But if we write y = (x + 2)^2, then we are translating two units to the left, and the lowest point is x = -2, y = 0.

Is the y axis the vertical axis?

YES it is!!! the X-axis is the horizontal one, you know, the horizon, something like that. so if you have a graph, Y is always up and down. X is always left and right. :)


How does you know that relation is a function?

One way is to try the vertical line test on a graph!


What did the derivative near the horizontal asymptote shout to the derivative near the vertical asymptote?

I don't know, what?


If you create two line segments one vertical and the other horizontal to connect with line segment GH to form a right triangle how long will the vertical and horizontal line segments be?

To determine the lengths of the vertical and horizontal line segments needed to form a right triangle with line segment GH, you need to know the coordinates of points G and H. The vertical line segment will be the difference in the y-coordinates of G and H, while the horizontal line segment will be the difference in the x-coordinates. If, for example, G is at (x1, y1) and H is at (x2, y2), then the vertical length is |y2 - y1| and the horizontal length is |x2 - x1|.


How you will know that the graph and the given equation into variables represent a function?

The graph or function relates a value y (in the vertcal direction) to a value x (in the horizontal direction). For each point x in the domain, there must be one and only one value y. In terms of a graph that means that a vertical line from any value of x in the domain must meet the graph in exactly place - at least once and not more than once. More than one x values can have the same y value associated with them.

Is the X axis vertical or horizontal?

Oh, dude, the X axis is horizontal. It's like the foundation of a graph, you know, where all the action happens left to right. If the X axis were vertical, we'd have a whole new set of problems... but thankfully, it's horizontal and life goes on.

How do you know there is no motion on a distance time-graph?

distance = velocity x time so on the graph velocity is slope. If slope is zero (horizontal line) there is no motion


How would you gaph the equation y equals 2x minuis3?

You know that y = 2x - 3, so to draw the graph: (a) You work out where this equation meets the horizontal axis of the graph and put a mark there. (b) You also work out where it meets the vertical axis of the graph and put a mark there. You then draw a straight line through the two points which carries on on either side. For (a) the equation meets the horizontal axis when y = 0. You know that y = 2x - 3, so put y = 0 into this equation. 0 = 2x - 3 -> 3 = 2x -> x = 1.5 So the line meets the horizontal axis when x = 1.5 For (b) the equation meets the vertical axis when x = 0 So again put that into y = 2x - 3 So y = 2*0 - 3 -> y = -3 So the line meets the vertical axis when y = -3. Draw a line through these two points (1.5,0) and (0,-3) and there you have your graph.
