Answer Key: A-Level Maths H2 Quiz - Graphs Coordinate Geometry

Section A: Fundamental Graphing & Transformations

Asymptotes: Vertical $x=3$ , Horizontal $y=2$ . Intercepts: $(0, -1/3)$ and $(-1/2, 0)$ .
Transformations:
- Translation by $\begin{pmatrix} -3 \\ 0 \end{pmatrix}$
- Stretch parallel to $y$ -axis by scale factor 2
- Reflection in $x$ -axis
- Translation by $\begin{pmatrix} 0 \\ 1 \end{pmatrix}$
Vertex: $(2.5, 0)$ . Endpoints: $(-1, 7)$ and $(4, 3)$ .
$y' = 3x^2 - 6x - 9 = 3(x-3)(x+1)$ $y^{'} = 3 x^{2} - 6 x - 9 = 3 (x - 3) (x + 1)$ .
- Max at $(-1, 10)$
- Min at $(3, -22)$
$y$ -intercept: $(0, -3)$ . $x$ -intercept: $(\frac{1}{2}\ln 4, 0) \approx (0.693, 0)$ . Asymptote: $y=-4$ .

Section B: Graphing & Curve Analysis

Max point: $(0, 1)$ . Graph is a bell-shaped curve symmetric about $y$ -axis, $x$ -axis is horizontal asymptote.
$x$ -intercept: $(-1, 0)$ . Vertical asymptote: $x=-2$ .
$\frac{x^2}{4} + \frac{y^2}{9} = 1$ (Ellipse).
Intercepts: $(\pm 2, 0)$ and $(0, \pm 3)$ .
$y^2 = x(x-3)^2$ or $y^2 = x^3 - 6x^2 + 9x$ .

Section C: Coordinate Geometry & Implicit Curves

Perpendicular slope: $-4/3$ . $y - 5 = -\frac{4}{3}(x - 2) \implies 4x + 3y - 23 = 0$ .
Perpendicular line through origin: $y = -\frac{1}{2}x$ . Intersection: $-\frac{1}{2}x = 2x + 1 \implies x = -0.4, y = 0.2$ . Point: $(-0.4, 0.2)$ .
$2x + 2y + 2x\frac{dy}{dx} + 6y\frac{dy}{dx} = 0 \implies \frac{dy}{dx} = -\frac{x+y}{x+3y}$ .
$\frac{dy}{dx} = 0 \implies x+y = 0 \implies x = -y$ . Substitute into $x^2 + 2xy + 3y^2 = 12$ : $(-y)^2 + 2(-y)y + 3y^2 = 12 \implies 2y^2 = 12 \implies y = \pm \sqrt{6}$ . Points: $(-\sqrt{6}, \sqrt{6})$ and $(\sqrt{6}, -\sqrt{6})$ .
$y' = 2x - 4$ . At $x=1, y=0$ and $y' = -2$ . Equation: $y - 0 = -2(x-1) \implies y = -2x + 2$ .

Section D: Complex Loci & Statistical Graphs

Circle centered at $(1, 1)$ with radius 2.
Half-line starting at $(2, 0)$ extending at $45^\circ$ angle.
Perpendicular bisector of the segment joining $(1, 0)$ and $(0, -1)$ . Equation: $y = x - 1$ .
Hyperbola in 1st quadrant and logarithmic curve passing through $(1,0)$ .
Exponential growth curve. Horizontal asymptote: $y=0$ .
