Answer :
The pair of functions are f(a) = 5 + a² and g(a) = √(a - 5) - 2 option third is correct.
What is a function?
It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
(gof)(a) = |a| - 2
Let f(a) = 5 + a²
g(a) = √(a - 5) - 2
(gof)(a) = g(f(a)) = √(5 + a² - 5) - 2
(gof)(a) = |a| - 2
Thus, the pair of functions are f(a) = 5 + a² and g(a) = √(a - 5) - 2 option third is correct.
