Question

Can someone please help????

Answer 1

Option C [-3, ∞).

Explanation:

In the given function f(x) = √(x+3) when drawn graphically we see that the graph has a growth starting form x=(-3).This can be evaluated by drawing a tangent on every point of the graph.

Here the graph is increasing form (-3) to ∞ which is the domain of the function.

Therefore the function is increasing over the interval of [-3, ∞).

Hence Option C is the correct answer.

Answer 2

Choice A is the correct answer

Explanation:

The function is increasing in the interval from -3 inclusive to infinity which is never inclusive
