Answer:
The correct option is A.
Step-by-step explanation:
If the degree and variables of two terms are same, then they are called like terms.
In option A.
The given expression is
Here, 4ab and -3ab are like terms because both have same variables a and b with degree 1.
By combining like terms we get
In options B, C and D, there are no like terms, So only the expression we can simplify by combining like terms.
Therefore the correct option is A.
Answer:
amplitude = 3
Step-by-step explanation:
The standard form of a cosine function is
f(x) = a cos(bx + c) + d
amplitude = | a |, period =
phase shift = - , d is the vertical shift
Given the above function, then
amplitude = | - 3 | = 3
