On the attached diagram you can see all graphs of functions b(x), d(x), m(x) and p(x).
Finding the inverse of a function f(x):
1. First, replace f(x) with y. This is done to make the rest of the process easier.
2. Replace every x with a y and replace every y with an x.
3. Solve the equation from Step 2 for y. This is the step where mistakes are most often made so be careful with this step.
4. Replace y with In other words, you’ve managed to find the inverse.
5. Remember: the domain of f is the range of and the range of f is the domain of
.
Using this algorithm, you can find the inverse only in case C:
for m(x)=-7x:
1. y=-7x.
2. x=-7y.
3. y=-x/7.
4. .
5. The domain and the range of m(x) are all real numbers as well as the domain and the range of
Functions b(x) and p(x) are not one-to-one functions (see attached diagram), then you can't find an inverse function. Function d(x) doesn't include x, then you can't also find an inverse function.
Answer C
y=-7x ==>x=-7y==>y=-x/7 is the inverse of m(x)

Answer:
convenience sampling is the correct answer.
Step-by-step explanation:
A convenience sample is a type of non-probability sampling method where the sample is taken from a group of people easy to contact or to reach.
For example: standing at a mall or a grocery store and asking people to answer questions would be an example of a convenience sample.
This type of sampling is also known as grab sampling or availability sampling. There are no other criteria to the sampling method except that people be available and willing to participate.
In addition, this type of sampling method does not require that a simple Random sample is generated, since the only criteria is whether the participants agree to participate.
