Answer:
Step-by-step explanation:
Domains of functions are the values that <em>can</em> be plugged into the function and not "break" it. By "break" I mean that the denominator cannot be 0, in this case. If the denominator is 0, we will get a divide by 0 error, and thus, we must restrict the domain. All values of x will work except 9/4:
![\frac{7-3x}{4x-9}](https://tex.z-dn.net/?f=%20%5Cfrac%7B7-3x%7D%7B4x-9%7D%20%20)
Let's plug in 9/4 and see what happens:
![\frac{7-3(\frac{9}{4})}{4(\frac{9}{4})-9} = \frac{whatever}{0}](https://tex.z-dn.net/?f=%20%5Cfrac%7B7-3%28%5Cfrac%7B9%7D%7B4%7D%29%7D%7B4%28%5Cfrac%7B9%7D%7B4%7D%29-9%7D%20%20%20%3D%20%5Cfrac%7Bwhatever%7D%7B0%7D%20%20)
So, plugging in 9/4 results in denominator equalling 0. Therefore, we must restrict the domain so that x ≠ 9/4. Your answer is All real values of x such that x ≠ 9/4.
