Question 1045706
<font face="Times New Roman" size="+2">


a.  Let's deal with the range first.  An item of jewelry cannot have less than zero percent gold and it cannot be more than 100 percent gold.  Hence, a valid real-world range for this function is *[tex \Large \left\{g\ |\ 0\ \leq\ g\ \leq\ 100\right\}].


Then, solving for *[tex \Large k] using the extreme values of the range, we get a domain of *[tex \Large \left\{k\ |\ 0\ \leq\ k\ \leq\ 24\right\}]


b.  It is a linear function with a slope of *[tex \Large \frac{25}{6}] that intercepts the axes at the origin.


c.  Substitute 100 for *[tex \Large g] and then solve for *[tex \Large k]
