Answer:
12. x = 48
13. x = 7
Step-by-step explanation:
x/6 = 8
x = 8*6
x = 48
28 = 4x
28/4 = x
x = 7
Domain are all the possible x values of a function. When you look at a cosine graph you can see that it goes on into infinity in the x or horizontal direction. This means that all x values are included in cosine. Because of this the domain is:
all real numbers
or
(-∞,∞)
^^^ It can be written both ways
Hope this helped! Let me know if there is anything else I can do!
