A function assigns the values. The cost of 6 CDs will be $32.
<h3>What is a Function?</h3>
A function assigns the value of each element of one set to the other specific element of another set.
Given that the Recycled CDs. Incorporated, offers a choice of 5 used CDs for $27, with each additional CD costing $5. Therefore, a cost function for purchasing 5 or more CDs, where x represents the number of CDs over 5 can be written as,
C(x) = $27 + $5(x)
Now, if 6 CDs are purchased then the number of CDs that are more than 5 is 1. therefore, the cost of 6 CDs will be,
C(1) = $27 + $5(1)
= $27 + $5
= $32
Hence, the cost of 6 CDs will be $32.

Dy/dx = (dy/dt) / (dx/dt)
dy/dt = 2bt
dx/dt = 3at^2
therefore dy/dx = 2bt/3at^2
dy/dx = 2b/3at
Answer:
The solution to the graph are x = -2 and x = 2
Step-by-step explanation:
Here, we want to get the solution to the graph
As we can see, the graph is parabolic; which is a property of a quadratic polynomial
The solution refers to the value at which the graph plot crosses the x-axis
In other words, the solutions to the graph are represented by the point at which we have the graph crossing over the x-axis
We can see this happen at two points
These are the points x = -2 and x = 2
