What is the range of the function y = 3x + 4?

  1. All real numbers

  2. All whole numbers

  3. All positive real numbers

  4. All negative real numbers

The correct answer is: All real numbers

The range of the function y = 3x + 4 is all real numbers because for any given x value, the function will output a corresponding y value that could be positive, negative, or zero. Therefore, the range includes both positive and negative real numbers, making options B, C, and D incorrect. Additionally, since the function includes a variable (x), the range will also include all numbers, making option A the most complete and accurate answer.
