Answer:
Option C . 2(5x – 1)
Step-by-step explanation:
we know that
The total number of CDs is equal to the CDs bought by Samuel plus the CDs bought by Joyce.
so
----> expression A
To find out the amount of discount for all of their CDs, multiply the total number of CDs by $2
so
Multiply the expression A by $2
Answer:
If you mean percent, its 350%
The function f(x) = x² then the required function exists g(x) = -x²- 4.
<h3>What is a function?</h3>
The function exists described as y = f(x).
In mathematics, a function from a set X to a set Y allocates to each element of X exactly one element of Y. The set X exists named the domain of the function and the set Y exists named the codomain of the function. Functions stood originally for the idealization of how a variable quantity relies on another quantity.
For every x there exists a certain value of y.
From the graph g(x) exists reflection of f(x) at y = -4.
So g(x) = -f(x) - 4, the negative sign for reflection.
g(x) = -x² - 4
The required function exists g(x) = -x² - 4.
Therefore, the correct answer is option D. g(x) = -x² - 4.
