Question

Fig. shows a sketch of a graph of y=(x-1)^2 for x is less than or equal to 0 the line PQ is the normal to the curve at the point (2,1)
A) find the equation of PQ given that PQ intersect the x-axis Q.
B) find the coordinates of the point Q.the finite region A is bounded by the curve y=(x-1)^2, THE X-axis and the line PQ.
C) calculate the area of the region A.
