Answers:
* -7
(b) (-3, ∞)
Work/for part (a) and explanation for part (b):
f ( x ) = x – 5 and g(x) =√ x+3
[a] f/g(-2)= (x – 5) / (√ x+3)
Replacing x with -2
f/g = (-2-5)/ (√ -2+3)
=-7/ √ 1
But √ 1=1 hence the answer is -7
[b] the quotient is = (x – 5) / (√ x+3) or [√ x+3 (x-5)] / x+3
The domain of the quotient is (-3, ∞)

Answers:
* 2 √ 17
* (-3,5)
* (3,5)
Work for part (a):
Work:
(1,4), (-7,6)
(x+3)2 + (y-5)2= 17
(1+3)2 +(4-5)2=17
R2= 17
