The answer depends on the form of the expression in the denominator. For example, the graph os 1/(1 + x2) has a pretty well-behaved graph, with a maximum vaue of 1 when x = 0 and asymptotes of y = 0
Some graphs do, but some don't. It depends upon the variables.
They are hyperbolae.
graphs give a trend of variables and the trend can be studied using the the extent they usually portray and the graphs are not emperical methods they give interpolated relationships hence a reduced uncertainities
Where they all intersect.
Solve for variables using equations graphs and tables. There is also a lot of substituting
Graphs are a convenient way to display relationships between variables.
They illustrate the relationship between two (or more) variables.
Represent two variables on two axes.
Some graphs do, but some don't. It depends upon the variables.
They are hyperbolae.
x and y
If two graphs have exactly the same shape, it indicates that the variables are proportional to each other. This means that as one variable increases or decreases, the other variable changes in a consistent and fixed ratio.
graphs give a trend of variables and the trend can be studied using the the extent they usually portray and the graphs are not emperical methods they give interpolated relationships hence a reduced uncertainities
Where they all intersect.
There are variables that have a cubic relationship: for example, the side of a cube and its mass.
Solve for variables using equations graphs and tables. There is also a lot of substituting
a bar grapg can be used
