Difference between subset and proper subset
To answer this question, I will use the following illustration.



In the above sets, set B is a proper subset of set A because all elements of B can be found in A, but not element of A can be found in B.
Set C is a subset of A because 
Using the above illustration, we have:
and 
is a subset of
, because 5 and 8 are in
but 2 which ca be found in
is not in 
2 because you do what is in parenthesis first :)
The equation in the vertex form of g(x) is:

<h3>
How to get the equation of function g?</h3>
We know that g(x) is a translation of 2 units below and 3 units to the left of f(x).
So first, let's rewrite f(x) to its vertex form:

The vertex is at:

The y-value of the vertex is:

Then the vertex form of f(x) is:

If we move this vertex 2 units below, and 3 units to the left, then we have:

That is the equation for g(x) in vertex form.

Step-by-step explanation:
To calculate the travel speed per hour, divide 120 by 3. 120/3 = 40 mph. Now to calculate the time it will take to travel 200 miles, divided 200 by 40 mph. 200/40 = 5
