The equation of a curve is y = 4x + px + qx where p and q
Question:
The equation of a curve is y = 4x³ + px² + qx where p and q are positive constants.
i) Show that the curve has only one stationary point when p = 23√q.
ii) In the case where p = 1/2 and q = −6, find
the set of values of x for which y is a
decreasing function of x.
