The degree of a polynomial is the highest power of the polynomial.
The polynomial is 
The degree is given as:

The zero is given as:

Add 3 to both sides

From the question, we understand that the polynomial has a single zero.
So, the polynomial is:

Substitute 4 for n

Hence, the polynomial is

Answer:

Step-by-step explanation:
Im assuming the question was
if thats not the case then im wrong
It helps you know what to multiply and the product when you subtracting and adding fractions.
Step-by-step explanation:
Putting both functions into a graphing calculator, we can easily find the domain and range. (attatched)
By looking at the graph, we can tell that f(x) is a quadratic function because of the symmetry. We can also tell that it never goes below 4. Knowing this, we can determine the domain and range.
Domain: {x | all real numbers}
Range: {y | y > 4}
By looking at the graph, we can tell that g(x) is an exponential function because it has a curve, and never goes below the x. Knowing this, we can determine the domain and range.
Domain: {x | all real numbers}
Range: {y | y > 0}
