What is the family of curves represented by the equation y = a sin(bx + c)?
Correct Answer: Sine waves
- Step 1: Identify the equation given, which is y = a sin(bx + c).
- Step 2: Understand that 'a' represents the amplitude of the sine wave, which is the height from the center line to the peak.
- Step 3: Recognize that 'b' affects the frequency of the wave, which determines how many cycles occur in a given distance.
- Step 4: Note that 'c' is the phase shift, which moves the wave left or right on the graph.
- Step 5: Conclude that changing the values of a, b, and c will create different sine waves, forming a family of curves.
