1) Find the coordinates of the centre and the radius of each circle and then graph them, showing the intercepts with the axes, and write down the domain and range of each.
a) x2 + y2 = 16 b) x2 + y2 = 1/25 c) x2 + y2 = 0.36 d) x2 + y2 = 64/9 2) For the curve x2 + y2 = 100, fill in the table of values and use it to help you draw the curve, then state the domain and range.
3) Sketch each function and state the centre, domain and range and clearly mark any points of intersection with the axes
