- The demand equation for a market is given by:
q(1 + 2 ln p) = 2
(a) Show that the elasticity of demand is equal to the inverse demand function.
(b) Hence, determine the range of values of p such that the elasticity of demand will be elastic.
- Let for values of x where it is defined.
(a) Find all the x and y-intercept of the curve y = f(x).
(b) Find all the horizontal and vertical asymptotes of the curve y = f(x).
(c) Find and classify all the stationary points of f(x).
(d) Sketch the curve y = f(x).
- Show that the function f is given by
f(x, y) = y² − 4xy + 4x² + x²y²,
has just one stationary point, and classifies it.
