曲线绘制是一种将给定方程解释为图形的方法。更具体地说，这使学生能够以遵循大学数学的方式直观地表示极限行为。在 HSC 中，曲线绘制主要是一个扩展 2 主题。但是，基本图形通常会在扩展 1 中被询问。
Let f ( x ) = − x 2 + 6 x − 8. {\displaystyle {\text{Let }}f(x)=-x^{2}+6x-8.}
On separate diagrams, and without using calculus, sketch the following graphs. {\displaystyle {\text{On separate diagrams, and without using calculus, sketch the following graphs.}}} {\displaystyle } Indicate clearly any asymptotes and intercepts with the axes. {\displaystyle {\text{Indicate clearly any asymptotes and intercepts with the axes.}}} {\displaystyle }
