Using the value of the graph we can say that the the function is negative x² because there are x-intercepts and the y-intercept if above 0.
Using the x-intercepts we can form the function of the graph:
-(x + 1)(x - 3) - we have a negative in front of the two brackets because the function is a negative. Now we multiply out the brackets and the negative at the end:
This the concept of geometry, we are required to get the coordinates of the point p which is the center of the circle. The center of the circle will be at the point: (x,y) =[(6-1)/2,(6-3)/2] =(5/2,3/2)
