# Thread: How would you write this out?

1. ## How would you write this out?

A company produces very unusual CD's for which the variable cost is $8 per CD and the fixed costs are$50000. They will sell the CD's for $83 each. Let x be the number of CD's produced. Write the total cost as a function of the number of CD's produced.$

Write the total revenue as a function of the number of CD's produced.
$Write the total profit as a function of the number of CD's produced.$

Also how would you write this out Given f(x)=|x| , after performing the following transformations: shift to the left 36 units, shrink vertically by a factor of 1/91, and shift downward 49 units, the new function
Use abs(x) for . I wrote it out as 1/91(x+36)^2-49 but it said its incorrect. So what would be the right way

You are not dealing with squares but with absolute values. Therefore the term reads:

$\displaystyle \frac1{91} \cdot |x+36| - 49$ or: (1/91)*abs(x+36) - 49
