A 2-column table with 4 rows. The first column is labeled x with entries negative 6, negative 1, 0, 3. The second column is labeled y with entries negative 7, 1, 9, negative 2. What is the domain of the given function? {x | x = –6, –1, 0, 3} {y | y = –7, –2, 1, 9} {x | x = –7, –6, –2, –1, 0, 1, 3, 9} {y | y = –7, –6, –2, –1, 0, 1, 3, 9}

I think the answer should be option one.

Step-by-step explanation:

I'm not sure

{x | x = –6, –1, 0, 3}  

Step-by-step explanation:

We know nothing of the function other than it has solutions for inputs (x) of -6, -1, 0, 3.  We don't know if any other inputs have a valid output.  The only x values, the domain, for which we have information are {x | x = –6, –1, 0, 3} .

step-by-step explanation:

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92
