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.

Give the horizontal asymptote, if there is one, of the graph of the equation
Give the horizontal asymptote, if there is one, of the graph of the equation
To find the horizontal asymptote, we can divide both numerator and denominator in the right expression by 
:
As 
approaches positive or negative infinity, 
and 
both approach 0. Therefore, 
approaches

Electrical power can be generated by wind, and the magnitude of power will depend on the wind speed. A wind speed of 
(in 
) will generate a power of 
. What is the minimum wind speed needed in order to power a device that requires 
?
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,
and factor, use the quadratic equation, or graph this on a calculator to find the root.
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 
. So we need factors of 
that when added together give us 
.
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 
.

If you look at
The graph shifts ten units to the right. The number inside the parentheses shows where and how many units the graph will shift. If it is in the parentheses with the x-coordinate, then it will shift either to the left or right. If the number is negative, it goes to the right. If it is positive, it will shift to the left.
If the number was with the y-coordinate then the graph would shift up and down.
