a)-144
b)36
c)-36
d)144
A general cosine function has the form:
f(x) = A*cos(c + x)
We want to find the value of A that matches the one in the image, and we will find that A = 3
Ok, a general cosine function is:
f(x) = A*cos(c + x)
Where A is the amplitude.
To find the amplitude of a cosine function, we just need to find half of the difference between the maximum and minimum value of the function:
By looking at the given graph, we can see that the maximum is y = 3, and the minimum is y = -3
Then the amplitude is:
A = (3 - (-3))/2 = 6/2 = 3
The correct option is B.
