Answer:
B - 10 (possibly and hopefully)
Answer:
Step-by-step explanation:
To find the inverse of a function, begin by switching the places of the 'y' and 'x' variables. Instead of f(x), we will substitute in 'y' for this purpose.
Substitute in 'y':
Swap the 'y' and 'x':
Square both sides:
Simplify:
**Keep in mind, when finding the inverse of a square root function, there is always going to be a restricted domain. In this instance, the restricted domain is
X-5=3 as the square root of 9 is 3
X=8 plus 5
Hope this helps
