Answer:

Step-by-step explanation:
The coefficient of a polynomial expression is the coefficient of the term with the highest exponent. We can see that the term with the highest exponent is
. So, the leading coefficient is its coefficient which is
.
Note that any number can be written as the product of that number and
as multiplying by
does not fundamentally change that number. In our given example,
is equivalent to
.
Answer:

Step-by-step explanation:
Based on the description, the Cosine function is of the form;

Where |a| is the amplitude. We have that the amplitude is 4 so a=4.
The period is given as

This can help us find the b-value.

The vertical translation is 3 units down so c=-3.
Hence the equation is
