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. <u>Domain </u>and <u>Range</u> 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.
