Question

Sketch the graph of $y=9+3x-2{{x}^{2}}$, indicate clearly the turning point and cutting point(s) on the axes. Hence, find the maximum or minimum point of the function and the value of $x$ where it occurs, the equation of the line of symmetry of the graph.

Accepted Answer

(i) Maximum point $\left(\frac34,\frac{81}{8}\right)$ at $x=\frac34$ (ii) $x=\frac34$
