What is the definition of a circle graph?
It is a graph of all points which are are the same distance (the radius) from a fixed point (the centre).
How do you determine if the points on a graph are invalid?
Plug the x-values into the original equation. If you get the same y-values, then the points are valid.
How would you determine whether two tables of values represented the same linear graph?
Plot all the points on the same coordinate grid. If they all lie on the same line then it is probably that they represent the same linear graph. I said probably because it is always possible that the points are not defined by a linear relation. Given any set of n collinear points, it is always possible to find a polynomial of degree n which will pass through each one of them.
How do you measure slope?
It is the derivative of the vertical change relative to the horizontal change - if the derivative exists. So, with the typical x-y graph, it would be dy/dx. If the graph is a straight line, then it is the change in the vertical positions between any two points divided by the change in the horizontal positions between the same two points (in the same order).
When using the Regression tools you cannot plot the points of your data and your model on the same graph?
False
How you can obtain the solution to a system of equations by graphing?
In the same coordinate space, i.e. on the same set of axes: -- Graph the first equation. -- Graph the second equation. -- Graph the third equation. . . -- Rinse and repeat for each equation in the system. -- Visually examine the graphs to find the points (2-dimension graph) or lines (3-dimension graph) where all of the individual graphs intersect. Since those points or lines lie on the graph of each individual graph, they are the solution to the entire system of equations.
Is a set of points in a coordinate plane the graph of a function if and only if no two points on the graph lie on the same horizontal line?
Of course not.The graph of [ f(x) = 4 ] is the straight line [ Y = 4 ] . . . a perfectly good function with all of its points on the same horizontal line.The graph of [ f(x) = x2 ] is the parabola with its nose at the origin and opening upwards. Another perfectly good function which has two points on every horizontal line [ Y = K ].In fact, I think probably every f(x) that has 'x to some power' in it always has at least two points on the same horizontal line.
What do you call a function whose graph is a non-vertical line?
It is a function. If the graph contains at least two points on the same vertical line, then it is not a function. This is called the vertical line test.
How can you obtain the average velocity from a displacement time graph?
-- Pick two points on the graph. -- Find the difference in time between the two points. -- Find the difference in displacement between the same two points. -- (Difference in displacement) divided by (difference in time) is the average Speed . You can't tell anything about velocity from the graph except its magnitude, because the graph displays no information regarding the direction of motion.
How do you determine invariant points of a graph algebraically?
Invariants are points that remain the same under certain transformations. You could plug the points into your transformation and note that what does in is the same as what comes out. The details depend on the transformation.
Why isnt it necessary for all of the data points to be on the drawn line of the graph?
The line of a graph is quite often used to indicate the average of various data points that fall both above and below the line. Very jagged lines get smoothed out, but the trend is the same.
How do you get half-life from a graph?
You can get half-life from a graph by picking two points where the (radio)activity decays to one half its value. The interval of time of those two points is the half-life. You can confirm by picking more points, again with a half (radio)activity value and see that the time is the same in each case.
