I have found the coordinates of Q (0,1) , by putting x=0 and solving f(x).Figure 1 shows the graph of y = f (x),

The graph consists of two line segments that meet at the point P.

The graph cuts the y-axis at the point Q and the x-axis at the points (–3, 0) and R.

given that

A) find the coordinates of P , Q and R.

B) solve

But I am not sure how to find R and P.

Also for part 'B',

should it be like this;
