Question 83

The deviation of a high-frequency oscillator from its resonance point is given by the function G(w)=∣3k−4w∣G(w) = |3k - 4w|G(w)=∣3k−4w∣, where w≥0w \ge 0w≥0 represents the angular frequency and kkk is a positive constant.

Sketch the graph of GGG against www. On your sketch, state the coordinates of the points where the graph meets the coordinate axes in terms of kkk.
