If \(y = 4x - 1\), list the range of the domain \({-2 \leq x \leq 2}\), where x is an integer.
Answer Details
The given equation is \(y = 4x - 1\), which represents a linear function where the output value of \(y\) depends on the input value of \(x\). The domain of the function is defined as the set of all possible input values of \(x\) that the function can take. Here, the domain of the function is given as \({-2 \leq x \leq 2}\), which means that \(x\) can take integer values between -2 and 2 (both inclusive).
To find the range of the function, we need to substitute the given values of \(x\) in the equation and calculate the corresponding values of \(y\).
When we substitute \(x = -2\), we get \(y = 4(-2) - 1 = -9\).
When we substitute \(x = -1\), we get \(y = 4(-1) - 1 = -5\).
When we substitute \(x = 0\), we get \(y = 4(0) - 1 = -1\).
When we substitute \(x = 1\), we get \(y = 4(1) - 1 = 3\).
When we substitute \(x = 2\), we get \(y = 4(2) - 1 = 7\).
Therefore, the range of the function for the given domain is {-9, -5, -1, 3, 7}.
