26 Here is the graph of \(\; y = x^2 - 2x - 2\)

Graph of y = x squared - 2x - 2 for x from -2 to 4, on a grid with y from -4 to 4. The curve has its minimum at (1, -3) and crosses the x-axis between -1 and 0 and between 2 and 3
(a) Write down the coordinates of the turning point on the graph of \(\; y = x^2 - 2x - 2\) (1)
(b) Write down an estimate for one of the roots of \(\; x^2 - 2x - 2 = 0\) (1)
