(a)[3]
Complete the table of values using $y = 8 + 7x - x^2$.
(b)[4]
Using the grid, sketch the graph of $y = 8 + 7x - x^2$ for $0 \le x \le 8$.
(c)[1]
State the co-ordinates of the highest point of the curve.
(d(i))[1]
Draw the line $y = 16$ on the grid.
(d(ii))[2]
Use your line to solve $8 + 7x - x^2 = 16$.
