D is the correct formula that the model represents. Black represents negative values, while white represents positive.
The domain are the x-values and the range are the y-values
Using the Fundamental Counting Theorem, it is found that she can choose 180 different meals.
<h3>What is the Fundamental Counting Theorem?</h3>
It is a theorem that states that if there are n things, each with
ways to be done, each thing independent of the other, the number of ways they can be done is:

In this problem:
- For the meat, there are 3 outcomes, hence
.
- For the two vegetables, 2 are taken from a set of 6, hence, applying the combination formula,
.
- For the dessert, there are 4 outcomes, hence
.
Then:

She can choose 180 different meals.

We have to find the domain of the given function

"The domain of a function is the set of input or argument values for which the function is real and defined"
Now, we have to find the values of 'x' for which the given function will be real and defined.
As we can observe that for any real number, the given function will be real and defined.
Therefore, the domain of the given function is
or
.
Or we can say that the domain of the given function is the set of all real numbers.
Well you would have to do 144 divided by 1/4 and you would get 36
