Question

match the key features of a sine graph to their corresponding values.1. 3 a. midline2. y = -1 b. amplitude3. 2pi c. frequency 4. 1 d. period

Answer 1

to find the amplitude, is the distance that separates the maximum or minimum point from the midline, in this case the amplitude is 3.

the midline is the line that divides the graph in half, in this case y=1

frequency is the number of times that the function is repeated in a period in this case is 1.

the period is how lond did it take for the wave to start again or to come to the start again after the frequency in this case is 2pi.
