fourth degree trinomial.
Step-by-step explanation:
we have
Classify the polynomial
Remember that
Polynomials can be classified two different ways - by the number of terms and by their degree
<u>1. Number of terms. </u>
In this problem we have tree terms . so is a trinomial
<u>2. Degree.</u>
The degree of the polynomial is found by looking at the term with the highest exponent on its variable(s).
In this problem the highest exponent is the so this is a fourth degree trinomial.

Answer:
minimum value of function is .
Step-by-step explanation:
Given function represents a parabola.
Now, here coefficient of is positive , so the parabola will be facing upwards and thus the function will be having a minimum.
Now, as we know that minimum value of a parabolic function occurs at
x = .
Where , b represents the coefficient of x and a represents the coefficient of .
here, a = 2 , b = -6
Thus =
=
So, at x = minimum value will occur and which equals
y = 2× -
+ 9 =
.
Thus , minimum value of function is .
