{dragpoint()}
We want to sketch a graph of the function $f(x) = \log_2(x)$. We will do this be plotting several points, and then seeing the overall pattern that emerges.
By filling in a table like the one below, drag the points A to H to the correct location.
| Point | A | B | C | D | E | F | G | H |
| $x$ | $\var{x[0]}$ | $\var{x[1]}$ | $\var{x[2]}$ | $\var{x[3]}$ | $\var{x[4]}$ | $\var{x[5]}$ | $\var{x[6]}$ | $\var{x[7]}$ |
| $f(x)$ |
(Note, to be marked correctly, you only need to move the points to within 0.1 of the exact location.)
Use this tab to check that this question works as expected.
