(a(i))[2]
Fill in the table of values for $y = -x^2 + 5x$.
(a(ii))[4]
Using the grid, sketch the graph of $y = -x^2 + 5x$ for $-1 \leq x \leq 6$.
(b)[1]
State the co-ordinates of the highest point on the graph.
(c)[2]
Use your graph to solve the equation $-x^2 + 5x = -3$.
(d(i))[1]
Using the grid, draw the line of symmetry for the graph.
(d(ii))[1]
State the equation of the line of symmetry for the graph.
(d(iii))[1]
Use the curve’s symmetry to determine the value of $k$.
