.
The set conjunction is
.
So the answer is B.
Hope this helps.
Answer:
X
Step-by-step explanation:
CAUSE
2X=X
DIVIDE BOTH SIDE BY 2 EQUAL ONE AND ONE IS EQUAL TO ( X)
To find the inverse of a function, firt we let

Now we switch x and y and solve for y .

Adding 25 to both sides

Now we need to get rid of square and for that we take square root on both sides. That is

Therefore, inverse is

Answer:
Step-by-step explanation:
Given are two functions f and g defined as

we have to find the composition of functions in all orders
1) 
![b) (fof)(x) = f{f(x)}=f(\sqrt{x} {=\sqrt[4]{x} \\\\When x=25, ans= \sqrt{5}](https://tex.z-dn.net/?f=b%29%20%28fof%29%28x%29%20%3D%20f%7Bf%28x%29%7D%3Df%28%5Csqrt%7Bx%7D%20%7B%3D%5Csqrt%5B4%5D%7Bx%7D%20%5C%5C%5C%5CWhen%20x%3D25%2C%20ans%3D%20%5Csqrt%7B5%7D)
