The cost for a company to manufacture "x"....
These statements tell you what X is. (The word cost refers to what the function will tell us. In other words C(x) = The Cost for the Company))
So as we keep going the problem goes onto:
.... bracelets
So the number of bracelets is X.
The function is: C(x)
And how functions work are quite simple. You plug in a number (x) and get out a number (y).
So, C(256) = 1536
So, they made 256 bracelets at a cost of 1536 dollars.
This is no different than if I said the function was:
C(x) = 6x
And then asked, what would the function equal when x = 256. It's the same thing, so don't let it trip you up!
Answer 1: 1536$
Answer 2: 256
The standard equation of circle when center is (h,k) and radius is 'r'

h = 2 and k = - 5, radius = 16
So equation of the circle is given by


You would want to make it into an addition problem that looks like this:
2x²+3x-4
+ x² - x - 2
___________
3x² + 2 - 6
The mean is the average of the numbers. to find the mean add up the numbers and divide by how many numbers there are
