Final answer:
The equation that represents the function puzzle is y = 3x + 4.
Step-by-step explanation:
The given function puzzle can be represented by the equation y = 3x + 4. The clue examples show that the output (y) is calculated by multiplying the input (x) by 3 and adding 4. For example, when x=2, y=10 because 3(2) + 4 = 10. Similarly, when x=5, y=19 because 3(5) + 4 = 19.
