One possible equation that represents the function is:
y = 2x, which can also be written as y = 2 * x.
Here's how the function values correspond to the equation:
When x = 1, y = 2 * 1 = 2
When x = 2, y = 2 * 2 = 4
When x = 3, y = 2 * 3 = 6
When x = 5, y = 2 * 5 = 10
And so on.
Note that there are other equations that could also represent the same function, but y = 2x is one possible option.
