Given the function y = a(trig function)(kθ + c) + d. What effect does (kθ + c) have on the graph of the parent function?
Added by Brandon H.
Step 1
The term "kθ" represents a horizontal compression or expansion of the graph. If |k| > 1, the graph is compressed horizontally by a factor of 1/|k|. If 0 < |k| < 1, the graph is expanded horizontally by a factor of 1/|k|. If k is negative, the graph is also Show more…
