An equal sign is a symbol in mathematics.
It is to indicate that the given terms are <span>equal.
It is also used to </span>indicate a mathematical <span>equality.
An equal sign looks like ( </span>

) this.
Given the function:

Let's find the amplitude and period of the function.
Apply the general cosine function:

Where A is the amplitude.
Comparing both functions, we have:
A = 1
b = 4
Hence, we have:
Amplitude, A = 1
To find the period, we have:

Therefore, the period is = π/2
The graph of the function is shown below:
The parent function of the given function is:

Let's describe the transformation..
Apply the transformation rules for function.
We have:
The transformation that occured from f(x) = cosx to g(x) = cos4x using the rules of transformation can be said to be a horizontal compression.
ANSWER:
Amplitude = 1
Period = π/2
Transformation = horizontal compression.
Answer:
Hi, there the answer is (4,2)
Step-by-step explanation:
The reason is that 4 is the y-axis and 2 is the x-axis and
the rule is x is first then y
The correct format for writing this it is supposed to be (2,4).
Therefore, your answer will (4,2)
This is a lot of math to write.... so I'll just say the answer is -21 :D
