Define h:R→Rh:\mathbb R\to\mathbb R by h(x)=∣2x−6∣+3h(x)=|2x-6|+3. (i) Show that hh is not one–to–one on R\mathbb R. (ii) Identify two disjoint intervals whose union is R\mathbb R such that hh becomes one–to–one on each interval. (iii) For every interval obtained in part (ii), find the corresponding inverse function. (iv) Sketch the graph of hh and the graphs of the inverses obtained, marking key points.
