Постройте график функции: y = log(x).
The graph of y = log(x) is a straight line passing through (0, 0) and (1, 1).
The graph of y = log(x) is a curve that starts at (0, 0) and rises steeply as x increases.
The graph of y = log(x) is a horizontal line at y = 1 for all x > 0.
The graph of y = log(x) is a curve that starts from negative infinity at x = 0 and passes through (1, 0), rising slowly as x increases.
