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 .

Height of one brick =
= 2.25 inch
Answer:
Step-by-step explanation:
b and c are the speeds of the boat and current, respectively.
Traveling upstream, the boat moves b-c km per hour.
Traveling downstream, the boat moves b+c km per hour.
b-c = (60 km)/(½ h) = (120 km)/h
b+c = (60 km)/(⅓ h) = (180 km)/h
Adding the equations together,
2b = (300 km)/h
b = (150 km)/h
c = (30 km)/h
The answer would probably be 18 degrees below normal because the absolute values of the rest are 8 not 18 which is the absolute value of 18 degrees below normal.
