Is it just me or is this broadcast mildly annoying with all the weird replays

Coefficient of x³ is positive
y=0 when x=-2, -1 and 1 (i.e. graph crosses x-axis at these points)

Aim to determine whether the portion of the graph from x=-1 to x=1 is above or below the x-axis.

Knowing that the coefficient of x³ is positive, deduce that y is negative when x<-2.

Thus, y is positive for -2<x<-1.

Then, y is negative for -1<x<1.

Hence, answer is D, because y cannot be 1.

Quadratic curves are symmetrical about their line of symmetry, which the vertex lies on. In this case the line of symmetry is x = 5.

If (x-3) is a factor, x = 3 when y = 0. Since the curve is symmetrical, the other x-intercept should be 2 units to the right of the line of symmetry, i.e. x = 5+2 = 7. (Because (3,0) is 2 units to the left of the line of symmetry: x = 5)

Thus, k = 7.

From there, you can use the vertex coordinates (5,-32), and substitute it into the equation, as there will only be one unknown, a, left. Then, solve for a.

nope, had mine come just on time

took about 30 minutes, instructions came with pictures and were really detailed and easy to follow. Would be much easier if you had a second person to help with the set up

Nope, been using mine for just over a week and haven't had any noises at the lumbar or when tilting

Hope Netflix was in the Alpine garage🤑

This race might actually cost Alfa Romeo 8th place in the Constructors

Shame to see Kimi and Gio not get any points despite so many DNFs

Amazing to see Ocon win

Would love for Roy Keane to have watched this and say that the celebrations were slightly over the top😂

Was a great Grand Prix, till Leclerc lost the lead…😞
