B. {−5,−4,−1,0,1,2,4,7}
C. {−5,0,1,2,4}
D. {5}

Answer 1

the domain of f
is the x's that are used

Answer 2

@RainbowsxD do you see the domain now?

Answer 3

a?

Answer 4

yep
you know what the x's are
because the one column is labeled x
so yes the x's that get used are -4,-1,0,-,2,7
and therefore the domain is {-4,-1,0,-2,7}
