The diagram shows the graph of the function $f(x) = ext{log}_2 x$, where $x > 0$ - Scottish Highers Maths - Question 9 - 2023

In summary, when sketching this graph, maintain the characteristics:

• The graph should remain concave up above the x-axis for $x > 0$.
• It must pass through $(0, 0)$ and $(1, 1)$,
• As $x$ approaches negative infinity, the curve approaches $y = -1$.
• Be mindful of ensuring a smooth curve without sharp corners as per typical behavior of exponential graphs.
