1. **Problem b:** Determine the equation of the parabola after transformation $(x,y) \to (x+4, \frac{1}{4}y)$ applied to $y=x^2$. 2. The original parabola is $y=x^2$.

1. **Problem Statement:** Solve the simultaneous equations graphically: $$2x + 3y = 12$$ and $$x - y = 1$$. 2. **Formulas and Rules:**

1.1.1 State the problem: Show that the equation of $f(x)$ is $-\frac{1}{2}x^2 - 2x + \frac{5}{2}$. 1. Use points B(-5,0) and C(1,0) where $f(x)=0$ to establish equations.
