If \(y = 4x – 1\), list the range of the domain \({-2 \leq x \leq 2}\), where x is an integer.
- {-9, -1, 2,3, 4}
- {-9, -2, 0, 1, 7}
- {-5, -4, -3, -2}
-
{-9, -5, -1, 3, 7}
The correct answer is: 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}.
