The degree of the polynomial function f(x) is 4.
Leto [7]

See the graph below

<h2>Explanation:</h2><h2></h2>

A polynomial function whose degree is 4 is given by the form:

f(x)=ax^4+bx^3+cx^2+dx+e \\ \\ Or: \\ \\ f(x)=a(x-x_{1})(x-x_{2})(x-x_{3})(x-x_{4}) \\ \\ \\ Where: \\ \\ x_{1},x_{2},x_{3} \ and \ x_{4} \ are \ the \ roots

Here the roots are:

x_{1}=-8 \\ \\ x_{2}=-5 \\ \\ x_{3}=1 \\ \\ x_{4}=2

If we set a=1 then:

f(x)=(x+8)(x+5)(x-1)(x-2)

Finally, by using graphing tool we get the graph of our polynomial function:
