General Form of Sine and Cosine

Question 1

Find a, b, and c for the function such that the graph of f matches the figure.

Revolt · Accepted Answer

a = 3, b = –2, c = π

Question 2

Use the drop-down menus to describe the graph.

Revolt · Accepted Answer

✔ 4; The amplitude of the graph is .: 4; The equation of the midline is .: y = 2; The period of the function is .: 3; The function is shifted left.: 0.5; The function is shifted units up.: 2

Question 7

Use the drop-down menus to complete each statement.

Revolt · Accepted Answer

✔ y = cos(2x) – 2; The function has the same amplitude as the function y = cos(x – 4) + 1.: y = cos(2x) – 2; The function is a translation of the parent cosine function.: y = cos(x) – 3

Question 8

y = 2cos(x)✔ y = cos(x) – 3y = cos(2x)y = cos(-2x)

Revolt · Accepted Answer

✔ y = cos(x) – 3
