Functions and Graph Transformations << Return to Index

General Tips:

1. When asked to sketch a transformed graph, e.g. f(x + 3), pick key points on the original graph to transform first (e.g. ones that go exactly through grid points, or y-intercepts, etc.) then join up with a line. This will ensure you draw it accurately.

2. Remember that changes inside the function brackets affect the x-axis and do the opposite of what you expect.

3. Learn the shape of y = sin(x), y = cos(x) and y = tan(x). In particular, learn that coordinates for which the graphs cross the x-axis, and the maximum/minimum points.

On to questions >>>

To get the curve perfectly mirrored, mirror points that go through squares first, i.e. (-4, 4), (-3, 1), (-1, 1), (0.4), then join up with a line.

#1: Use two arcs with radius the width of the line to form an equilateral triangle (only one side needed).This gives you an angle of 60.

#2: Find the angle bisector of these two lines in the usual way, in order to find the angle half of 60.
