Answer:
a
Step-by-step explanation:
Domain means the change in x.
so the domain will be which values of x the fn goes through.
you can see the black line goes from -9 to 2 in x values.
the -9 isn't filled in, but the 2 is. filled in means it will be with an equals instead of without.
so x is between -9 and 2, 2 is with equals -9 is without,
so the first one.
The value of x can be found using the sine function.
sin 30 = x/8
8 (sin 30) = x
4 = x

A has no real solution. See the picture below for details.
