Final answer:
The domain values for the function f(x) = 2x + 3 are (-2, 0, -0.5, 0.5).
Step-by-step explanation:
The domain values for the function f(x) = 2x + 3 can be determined by looking at the range values given. The domain represents the set of all possible input values for the function. In this case, since the range values are (-1, 1, 2, 4}, we can consider each of these values as the output of the function and solve for the corresponding input (x).
For example, if we substitute -1 for f(x), we get:
-1 = 2x + 3
Solving for x, we find x = -2.
Repeating this process for the other range values, we find that the domain values for the function f(x) = 2x + 3 are (-2, 0, -0.5, 0.5).
