Answer 1

To find the range of the function \( f(x) = 3x + 7 \) for the given domain \({-2, -1, 0, 1, 2}\), we will evaluate the function at each of the domain values.

1. For \( x = -2 \): \[ f(-2) = 3(-2) + 7 = -6 + 7 = 1 \]

2. For \( x = -1 \): \[ f(-1) = 3(-1) + 7 = -3 + 7 = 4 \]

3. For \( x = 0 \): \[ f(0) = 3(0) + 7 = 0 + 7 = 7 \]

4. For \( x = 1 \): \[ f(1) = 3(1) + 7 = 3 + 7 = 10 \]

5. For \( x = 2 \): \[ f(2) = 3(2) + 7 = 6 + 7 = 13 \]

Now, we compile the outputs: \[ f(-2) = 1, \quad f(-1) = 4, \quad f(0) = 7, \quad f(1) = 10, \quad f(2) = 13 \]

The range of the function for the given domain is: \[ {1, 4, 7, 10, 13} \]

So the correct answer is: \[ {1, 4, 7, 10, 13} \]
