Determine the initial value and the rate of change of the linear function.
1. The initial value is 0, and the rate of change is 1/2.
2. The initial value is 2, and the rate of change is 2.
3. The initial value is 0, and the rate of change is 2.
4. The initial value is −6, and the rate of change is 2.
1. The linear function is f(x) = (1/2)x + 0.
2. The linear function is f(x) = 2x + 2.
3. The linear function is f(x) = 2x + 0.
4. The linear function is f(x) = 2x - 6.
