Question

The graph of y = 4sin (3x + 2) + 1 has amplitude of:
Select one:
a. O
b. 1
c. 2
d. 3
e. 4

Answer 1

Answer: 4

Step-by-step explanation:  g(x) = A*cos(bx) + c When you see a function of the form f(x) = A*sin(bx) + c or g(x) = A*cos(bx) + c where A, b and c are constants, its amplitude is equal to A, the coefficient at sine or cosine.
