So it is given that f(x) and g(x) are inverse of each other.
Then f(5) = -7 and hence g(-7) = 5
Now let's use f( g( x ) ) = x
Now take deviation. Use chain rule:
f'( g(x) ) g'( x ) = 1
Plug in x = -7
f'( g( -7 ) ) g'( -7 ) = 1
f'( g( -7 ) ) · -2/3 = 1
f'( g( -7 ) ) = -3/2
f'( 5 ) = -3/2
Hope this helps.

Answer:
Area of semicircular lawn is 9.82 square meter.
Step-by-step explanation:
Given:
Diameter of the semicircle = 5 m
So we will find the radius.
Radius is half of the diameter.
Radius 
We need to find the area of the lawn.
Solution:
Now we know that;
Area of semicircle is half times π times square of the radius.
framing in equation form we get;
Area of semicircular lawn = 
Hence Area of semicircular lawn is 9.82 square meter.
