Question

What does this graph tell you about the domain and the range of this function? Please help :)

Answer 1

Answer:

Step-by-step explanation:

The domain is (-5, infinity).  There's no graph for x ≤ -5.

The range is [2, infinity).

Answer 2

Answer:

C. The domain is [-k, ∞), and the range is [C, ∞).

Step-by-step explanation:

To be able to answer this question we first need to understand what exactly are the domain and range of a function. Domain and Range can be defined as the following,

Domain: are all the possible input values a function can recieve, displayed as the x-coordinates on a graph.

Range: are all the possible output values that a function can spit out, displayed as the y-coordinates on a graph.

With this understood, we can look at the graph and easily point out the domain and range as the following values.

Domain being [-5,∞) ..... closed bracket because the value is included

Range being [2, ∞) ..... infinity values always take an open parenthesis

Based on this information we can safely assume the answer is C. The domain is [-k, ∞), and the range is [C, ∞).

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.
