Correct answers only and you , me the graph shown below expresses a radical function that can be written in the 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].

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180
