Given:
The function is

To find:
The inverse of the given function.
Solution:
We have,

Put f(x)=y.

Interchange x and y.

Isolate the variable y.




Putting
, we get

For
,




It means for function
and for inverse function
because the range of the function is the domain of inverse function.
Therefore,
for
.
Answer:
Step-by-step explanation:
If breadth =x
length =x+2
Area =length *breadth
Area =x(x+2)=80
X^2+2x-80=0
X^2 +10x - 8x - 80=0
X(x+10)- 8(x+10)=0
(X-8)(x+10)=0
X=8 or x=-10
X=8(since breadth cannot be a negative value x cannot be negative)
1.886 to the nearest hundredth would be 2.
I think yes because, for every person who leaves the community pool has a different opinion. So it may be valid or invalid.
