The required answer to the composition of the function is 0
What is composition of function?
If f(x) and g(x) are the two function then fog(x) and gof(x) are called composition of the two functions.
How to calculate composition function?
If we have to find fog(x) then make f [ g(x) ] then put the value of g(x) then solve for given f(x)
Here we have f (x) = x +1 and g (x) = 2x -7
Now fog(x) = f[g(x)] = f[2x-7]
Here 2x-7 will treat like x for the function f (x)
So fog(x) = 2x -7 + 1 = 2x -6
Now we have calculate fog (3)
Therefore
fog(3) = 2(3) -6 = 6-6 = 0
This is the conclusion to the answer.
