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.

I wasn't able to parse your question, but the HE.NET team is hard at work making me smarter.
