Suppose that the functions f and g are defined as follows: f(x) = 3x - 5 and g(x) = √(5x + 3). Find f + g and (f)/(g). Then, give their domains using interval notation. What is the expression for (f+g)(x)?
A) f(x) + g(x)
B) f(x) - g(x)
C) g(x) - f(x)
D) g(x) + f(x)
What is the domain of f+g?
A) [-[infinity], 3/5]
B) (-[infinity], 3/5]
C) [3/5, [infinity])
D) (-[infinity], [infinity])
