If (y = 4x – 1), list the range of the domain ({-2 leq x leq 2}), where x is an integer.
-
A.
{-9, -1, 2,3, 4} -
B.
{-9, -2, 0, 1, 7} -
C.
{-5, -4, -3, -2} -
D.
{-9, -5, -1, 3, 7}
Correct Answer: Option D
Explanation
The elements of x are {-2, -1, 0, 1, 2}
(y = 4x – 1) = 4(-2) – 1 = -9; 4(-1) – 1 = -5; 4(0) – 1 = -1; 4(1) – 1 = 3; 4(2) – 1 = 7.
The range of x is {-9, -5, -1, 3 7}.
