Answer:
![\frac{2808}{3125}](https://tex.z-dn.net/?f=%5Cfrac%7B2808%7D%7B3125%7D)
Step-by-step explanation:
X-7=18
+7 to both side
X=25
To solve this problem you must apply the proccedure shown below:
You must switch the variables, and then, you must solve for
, as following:
![x=-\frac{1}{2} \sqrt{y} +3\\ (x-3)^{2} = (\frac{1}{2}\sqrt{y})^{2} \\ y=4x^{2} -24x+36\\ f^{-1} (x)=4x^{2} -24x+36](https://tex.z-dn.net/?f=%20x%3D-%5Cfrac%7B1%7D%7B2%7D%20%5Csqrt%7By%7D%20%2B3%5C%5C%20%28x-3%29%5E%7B2%7D%20%3D%20%28%5Cfrac%7B1%7D%7B2%7D%5Csqrt%7By%7D%29%5E%7B2%7D%20%20%20%5C%5C%20y%3D4x%5E%7B2%7D%20-24x%2B36%5C%5C%20f%5E%7B-1%7D%20%20%28x%29%3D4x%5E%7B2%7D%20-24x%2B36%20)
Therefore, as you can see, the answer is: ![f^{-1} (x)= 4x^{2} -24x+36 ](https://tex.z-dn.net/?f=%20f%5E%7B-1%7D%20%28x%29%3D%204x%5E%7B2%7D%20-24x%2B36%0A)
