Complete the square and identify vertex features
The quadratic \(f(x)=-x^{2}+8x-10\) can be written as \(f(x)=-(x-4)^{2}+6\). State \(a\), \(h\), \(k\), the vertex, axis, and range.
Worked practice: quadratic features
Use the vertex-form information to state the graph features in order.
Write a full answer
Now write the response in full, in your own words — this is what the exam asks for. The AI marks it on the same moves you built above (focus, evidence, technique, judgement) and gives feedback on reasoning, evidence, and expression.
