What is the domain of the following graph? (Marking whoever gets it right Brainiest) Question 4 options:

{-4,-2,0,4}

{-1,0,2,4}

{1,2,3,4}

{-2,-1,0,1,2}

i think the answer is true

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

60: 45 =12: 9 =4: 3 so the answer is 4: 3
