HSC Exam Questions (Real Functions) 1995 HSC Q4(b) 4 (i) Draw the graphs of = || and = + 4 on the same set of axes. (ii) Find the coordinates of the point of intersection of these two graphs. 1997 HSC Q4(b) 6 (i) Sketch the graph of = ! − 6 and label all intercepts with the axes. (ii) On the same set of axes, carefully sketch the graph of = ||. (iii) Find the coordinates of the two points where the graphs intersect. (iv) Hence solve the inequality ! − 6 ≤ ||. 2000 HSC Q1(g) Sketch the line = 2 + 3 in the Cartesian plane. 2 2001 HSC Q5(a) State the domain and range of the function = 2 25 − ! . 3 2002 HSC Q6(a) Sketch the graph of = 4 − ! , and state the range. 2 2003 HSC Q3(c) Shade the region in the Cartesian plane for which the inequalities < − 2, ≥ 0 and ≥ 6 hold simultaneously. 2 2008 HSC Q8(a) Let = ! − 8 ! . (i) Find the coordinates of the points where the graph of = () crosses the and axes. 1 (ii) Show that () is an even function. 1 (iii) Sketch the graph of = (). 1 2009 HSC Q1(a) Sketch the graph of − 2 = 3, showing the intercepts on both axes. 2
