Step-by-step explanation:
To get an equivalent fraction, we multiply by a fraction that is equal to one. The purpose is to alter the denominator of the fraction. To get from a denominator of 7 to 21 we multiply by 3. Therefore we will multiply 5/7 by 3/3 to get the new equivalent fraction with a denominator of 21.

If we do not care about order, then a combination is an arrangement of r objects chosen from n distinct objects. It can often be seen written as:

or

Its factorial form is:
<h2>
Explanation:</h2><h2>

Here we have the following rational function:

So the graph of this function is shown in the First Figure below. Let's define another function which is a parent function:

Whose graph is shown in the second figure below. So we can get the graph of f from the graph of g this way:
Step 1. Shift the graph 3 units to the left:

Step 2. Shift the graph 2 units down:

Finally, the features of the graph of f are:
The graph of this function comes from the parent function g and the transformations are:
- A shifting 3 units to the left
