Question

What is the range of y = 5x -2 if the domain is {-3, -1, 0, 1, 3}?


{-13, -3, 2, 3, 13}

{12, 3, 0, 3, 13}

{-17, -7, -2, 3, 13}

Answer 1

please, note that if i substitute x=-3, into your function, I will get this:
\[y=f(-3)=5*(-3)-2=-15-2=-17\]
so, please do the same with the remaining values of x

Answer 2

oops..I call \[y=f(x)=5x-2\]

Answer 3

C

Answer 4

no, I don't think, because -17 doesn't belong to the set in B

Answer 5

yes! I think it is C
