Solution:
we are given that

we have been asked to find f(x).
we can find the value of f(x) by re-writing the given function in the form of f(x+3) and thereafter we will replace (x+3) by x.
we can re-write the given function as below

Hence the expression representing f(x) is f(x)=4x+3.
Answer: 701953087225 is the answer
Area of sector CAD = 72 / 360 x pi x 6^2 = 7.2pi = 22.6195 in^2
Therefore, area of segment CED = 22.6195 - 17.18 = 5.44 in^2
All you have to do is subtract 3/8 from 7 which would give you 9 and 1/3
