Finding Parameters of a Logarithmic Function
Secondary 3
The following shows the graph of \(y = k \log_{2}(1 - x) + a\).
The graph passes through the points \((0, -1)\) and \((-31, 9)\).
Find
- the value of \(a\).
- \(k\).
The source diagram is schematic and does not consistently represent the stated formula on its numbered scale. Use the two stated coordinates to determine the parameters.
