Example Question #1 : Graphing
A triangle is made up of the following points:
What are the points of the inverse triangle?
The inverse of a function has all the same points as the original function, except the x values and y values are reversed. The same rule applies to polygons such as triangles.
Example Question #1 : How To Graph Inverse Variation
Electrical power can be generated by wind, and the magnitude of power will depend on the wind speed. A wind speed of 
The simplest way to solve this problem is to plug all of the answer choices into the provided equation, and see which one results in a power of 
Alternatively, one could set up the equation,
If we were to factor we would look for factors of c that when added together give us the value in b when we are in the form,
In our case 
Thus the following factoring would solve this problem.
Then set each binomial equal to zero and solve for v.
Since we can't have a negative power our answer is
