Question

Find the domain of the composite function fg.

f(x) = 6x + 24; g(x) =
A) [-4, ∞)
B) (-∞, ∞)
C) [0, ∞)
D) (-∞, -4] or [0, ∞)

Answer 1

g(x)=\[\sqrt{x}\]

Answer 2

Since the square root of any number must be positive, because two numbers multiplied will cancel out the negative, the domain would be (c). All number from zero and up.

Answer 3

thank you I thought so. Most of the questions ended up the same.
