A curve is such that (dy/dx) = 4/√(6 − 2x), and P (1, 8)
is a point on the curve. The normal to the curve at the point P
meets the coordinate axes at Q and at R.
Find the coordinates of the mid-point of QR.
The diagram shows the curve y = x
3 − 3x
2 − 9x + k, where k is
a constant. The curve has a minimum point on the x-axis.
Find the value of k.
