CORRECT ANSWERS ONLY PLEASE AND THANK YOU , HELP ME The graph shown below expresses a radical function that can be written in th
e form f(x)=a(x+k)^1/n+c. What does the attached graph tell you about the domain and the range of this function?. A. The domain is [c, ∞) & the range is [-k,∞). B. The domain is [-k,∞) & the range is (-∞,c]. C. The domain is (-∞,∞) & the range is (-∞,∞). D. The domain is (-∞,k] & the range is [c,∞).
A negative number raised to a certain power is equal to an undefined value. In this case, the goal of the have x equal to -k and numbers greater than it. Hence the domain includes k and numbers to infinity. The minimum value of the range is negative infinity up to a value where the first term is zero or range equal to c.Hence the answer is B. The domain is [-k,∞) & the range is (-∞,c].
