B) draw the graph of y=-x^2+2x+1 on the grid below -3<x<5
-14<y<4

c) use your graph to find the solutions to the equations
-x^2+2x+1=0

d)i) on the grid, draw the line of symmetry of the graph
ii) write down the equation of this line of symmetry

e)i) draw the line y=-2 on the grid
ii) write down the coordinates of the interception of the two graphs.
