X-y graph
The y-Variable
Any metric or non-metric units can be represented by points on the plotted line.
If it is plotted correctly, there is no reason for it to be anything but accurate.
Scatter Graph
That's how "function" is defined. If you have two points with the same x-coordinates, you have a "relation", but not a "function". A function is a special type of relation. The idea of a function is that, for every value of the independent variable (for example, "x"), the dependent variable (for example, "y") is uniquely defined. In other words, you can consider a function as a rule that assigns a y-value uniquely to every x-value.

The independent variable in this experiment is the fingerprinting powders. The dependent variable is the points of minutiae, which are identifying points on a fingerprint.
"Player" is the independent variable, and "Points" is the dependent variable.
The zeros of a function are the values of the independent variable where the dependent variable has value of zero. In a typical representation where y = f(x), the zeroes are the points x where y is 0.
The y-Variable
a kind of example is the amount of sunlight * * * * * No it is not! The amount of sunlight given out by the sun depends on solar activity. It will be hugely greater in around 4.5 billion years when the sun becomes a red giant. The amount of sunlight incident on some point depends on the location of that point. Somewhere on Mercury will get a lot more sunlight than on Neptune! Also even if you restrict yourself to points on the earth, there are differences between latitudes, the time of year, cloud cover and so on. Even something that is apparently as independent of everything else, such as time, is not quite that independent. Gravity affects it. An independent variable is determined not by the variable itself but by the context of the "experiment". It is (or they are) variable(s) that affect the dependent variables but are not affected by them. An independent variable in one experiment may be the dependent variable in another. For example: age and height of people: I would say that age is independent and height is dependent. height and membership of basketball team: I would say height is independent and membership is dependent.
Any metric or non-metric units can be represented by points on the plotted line.
Select a number of different values for the independent variable (usually x). For each x, calculate the value of the dependent variable using the nonlinear equation. Call these f(x). On a Cartesian plane, mark the points whose coordinates are(x,f(x)) and join them by a smooth curve.
If it is plotted correctly, there is no reason for it to be anything but accurate.
Scatter Graph
All points on a contour line represent locations with the same value of the variable being plotted, such as elevation or temperature. Each contour line indicates a specific level or value of the variable, and points on the line have that exact value.
That's how "function" is defined. If you have two points with the same x-coordinates, you have a "relation", but not a "function". A function is a special type of relation. The idea of a function is that, for every value of the independent variable (for example, "x"), the dependent variable (for example, "y") is uniquely defined.
