<h2>
Explanation:</h2>
In this exercise, we have two cases and both will be polynomial functions with degree 3 because we have three real roots in each case. So:
<h3>First.</h3>
The roots are:
So we can write this polynomial functions as the product of linear factors:
Since we have to write it in standard form, let's expand:
<h3>Second.</h3>
The roots are:

Answer: A. h(x) = 205x - 56
Step-by-step explanation:
Since, According to the question,
The amount she earns for her seafood demos is given by f(x) = 85x - 21 where x represents the number of days.
And, The amount she earns for her cake decorating demos is given by g(x) = 120x - 35.
Therefore if h(x) represents total amount she earns in x days.
Then h(x)= f(x)+g(x)=85 x - 21 + 120 x - 35=205 x-56
⇒h(x)=205 x-56
Thus, Option A is correct.
