Key features of a quadratic
The function \(f\) is defined by \(f(x) = -x^{2} + 4x + 5\), for \(x \in \mathbb{R}\). Find the \(x\)-intercepts, the \(y\)-intercept, the axis of symmetry, the coordinates of the vertex, and hence state the range of \(f\).
Worked practice: read the quadratic graph
Work through the graph features in order. You can type plain text or LaTeX-style notation.
Write a full answer
Now write the solution in full, as you would in the examination. The AI checks the mathematical method or formula, substitution, algebra or calculation, notation, requested accuracy, and any interpretation or verification required by the command term.
