Question

Hello! 

I posted on this image below but wanted to ask for specific questions. I was wondering how to solve question 19. 

 

 

For each pair of functions in Exercises 17-32:
a) Find the domain of f, g.f+ &f - & fs ff. f/s.
and g/f.
b) Find (f + g)(x), (f – g)(x). (fg)(x), (ff)(x).
(fls)(x), and (g/f(x).
17) f(x) = 2x + 3, g(x) = 3 – 5x
18. f(x) = -x + 1, g(x) = 4x - 2
19.)f(x) x - 3, g(x) = Vx+ 4
20. f(x) = x + 2, g(x) = Vx-1
21. f(x) = 2x - 1, g(x) = -2x
22. f(x) x- 1, g(x) 2x + 5
23. f(x) Vx- 3, g(x)
Vx + 3
