The amplitude of the function is 3/2 after comparing with the general equation option (C) is correct.
<h3>What is cos function?</h3>
It is defined as the function which is in the form of cosine waves in nature, and it has a domain of all real numbers and lies between the [a, a] where is a amplitude of the function.
We have a cos function:
y = 3/2 cos(3x) + 1
We know,
f(x) = acos(bx - c) + d
The above function represents the cos function where:
a = amplitude
b = is the period of the function
c = phase shift
d = vertical shift
On comparing we get:
a = 3/2
Thus, the amplitude of the function is 3/2 after comparing with the general equation option (C) is correct.

Answer: 0.33 or 1.32 or 6.6%
Step-by-step explanation:
Answer:
Add 7 to both sides
Step-by-step explanation:
You would need to add 7 to both sides to cancel out the 7 on the right side of the equation to get x one step closer to being by itself.
Then you would get 4x = -8.
Next divide by 4 on both sides to get x by itself so do the inverse operation of what 4 was doing to x.
x = -2
Answer:
9
Step-by-step explanation:
three more than the sum of (3,3)
lets first do the sum of (3,3)
3 + 3 = 6
now it's asking<em> three more than the sum of (3,3)</em>
three more than means we need to add 3 to 6
6 + 3 = 9
