use differentiation and also completing the square method...to just recall ur f4c2 addmaths
Ah Ma’s festive cookie demand is modelled by the function:
y = x^2 e^x
where x is the number of days before Chinese New Year.
1️⃣ Find dy/dx
2️⃣ Find the stationary point(s)
3️⃣ Determine whether it is a maximum or minimum
Only true CNY addmath legends will survive this one 🥠📈

Q2. A box of festive cookies has a price modelled by the quadratic function:
f(x) = x^2 - 6x + 5
1️⃣ Factorise the expression.
2️⃣ Hence, find the values of x when f(x) = 0
f(x) = x^2 - 6x + 5

Q3. Two lanterns, A and B start to elevate from point O at the same time along a straight line in the same direction.
Lantern A travels a distance of p m in the first second and increases its distance travelled by q m for every subsequent second. If it travels a distance of 35 m in the 6th second and the total distance travelled in the first 10 seconds is 330 m, calculate the values of p and q. [4m]
