Question 121

Given that ppp and qqq are positive constants with p>qp > qp>q,

a.

Sketch, on separate diagrams, the graph with equation

(i) y=∣2x−p∣y = |2x - p|y=∣2x−p∣

(ii) y=∣2x−p∣−qy = |2x - p| - qy=∣2x−p∣−q

Show on each sketch

  • the coordinates of the minimum point on the graph
  • the coordinates of the point at which the graph crosses the yyy-axis
[4]
b.

Solve the equation

∣2x−p∣−q=4x |2x - p| - q = 4x ∣2x−p∣−q=4x

giving any solution for xxx in terms of ppp and qqq.
