1- To the nearest 1000, there are 18000 people at a festival.
(a)Write down the minimum possible number of people at the festival (b)Write down the maximum possible number of people at the festival.
2- The equation of a curve is y= (x– 1)2– 6
Circle the coordinates of the turning point.

nope :{ its not working for me
1. There are 18000 people rounded to the nearest thousand. This means that there can be a minimum of 17500 people, and a maximum of 18500
2. (x-1)^2 -6 = x^2 -2x - 6
You can either put this equation into https://www.desmos.com/calculator and look at the turning point (1,-6) or you can solve it using various methods.
The simplest one would be completing the square.
The equation is given as (x-1)^2 - 6
This conveniently gives you the y coordinate as -6 because it is on the outside of the brackets.
Then you sub y = 6 into the equation 6 = x^2 - 2x -6
= x^2 -2x
= x(x-1)
This tells you that there is a repeated root at x = 1
Therefore (1,-6)
