Answer:
option D
0.5
Explanation:
Formula to find the amplitude of function graph is
amplitude = maximum - minimum / 2
here maximum = 0.5
minimum = -.05
Plug values in the formula
amplitude = 0.5 - (-0.5) / 2
= 1 / 2
= 0.5
Secondly,
The amplitude of y=asin(x) and y=acos(x) represents half the distance between the maximum and minimum values of the function.
Amplitude = |a|
so,
y = .5cos6x
here a = 0.5
