Answer: B.) <em>The cost of a pizza with no toppings is $6 </em>
Step-by-step explanation:
<em>The y-intercept shown on the graph is (0,6)</em>
<em>Meaning with 0 toppings, the pizza cost </em><em>$6</em>
For this case we have a quadratic polynomial given by:

Where:

We must factor, for this we follow the steps below:
Step 1:
The term of the medium must be rewritten as the sum of two terms, whose sum is -7 and the product is
:
Then, the term of the medium, fulfilling the two previous conditions, can be written as:

We check:

So, we have:

Step 2:
The maximum common denominator (the largest integer that divides them without leaving residue) of each group is factored

Step 3:
We take common factor
:

Thus, the expression
can be factored as:

Answer:
