Express the polynomial −g + 3g + 2g2 in standard form and then classify it.
1 answer:
Standard Form of Polynomials: When each term is written in the [decreasing; greatest to least] order of degree.
__________________________________________________________
Note 1: A degree of a term is the number of it's exponent.
Note 2: A constant number (A number without an exponent) will have the degree of 0. Always.
Note 3: A variable without a visible exponent obtains an exponent of 1. Ex. x =
Note 4: The operation sign before a coefficient/constant indicates if it's positive or negative. No sign: it's positive. Subtraction sign: value is negative. Addition sign: value is negative.
Note: A degree of a polynomial is the number of it's highest exponent.
Note: (Mono)mials are polynomials with only one term. (Bi)nomials are of only two terms. (Tri)nomials are of only three terms. (Poly)nomials are more than 3 terms.
Mono - One
Bi - Two
Tri - Three
Poly - Many

Step 1: Find the degrees of all the terms1: -g translates to
This is the first degree.
2: 3g translates to
This is the first degree.
3: I am supposing you meant
for ''2g2''. If you did (most likely), you should do ^ to indicate if the number after that sign is an exponent while the number in front is the base. say for instance, x^2. This translates to 
where x is the base and 2 is the exponent. This is the second degree.
Step 2: Order them greatest to least.
comes first since it's the greatest degree. I'm putting 3g second even if 3g and -g shares the same degree because the number before the variable is greater than -g's number before the variable.
+ 3g -g

Classifying Polynomials: You can classify polynomials by degree and by the number of terms. First is the degree then then the type of polynomial.
In this case it's 2nd degree trinominal because the highest exponent in a term is 2 and there are three terms within this expression

Answer:
(D)On a coordinate plane, a parabola opens up with x-intercepts at (negative 2, 0) and (2, 0), and a y-intercept at the vertex (0, negative 4).
Step-by-step explanation:
For a parabola to have a minimum vertex, it must open upward. (a>0).
In the given options, the parabola which opens upward is option D.
On a coordinate plane, a parabola opens up with x-intercepts at (negative 2, 0) and (2, 0), and a y-intercept at the vertex (0, negative 4).
Therefore, it has a minimum vertex with coordinates (0,-4).
Not sure if you mean to ask for the first order partial derivatives, one wrt x and the other wrt y, or the second order partial derivative, first wrt x then wrt y. I'll assume the former.
Or, if you actually did want the second order derivative,
![\dfrac{\partial^2}{\partial y\partial x}(2x+3y)^{10}=\dfrac\partial{\partial y}\left[20(2x+3y)^9\right]=180(2x+3y)^8\times3=540(2x+3y)^8](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Cpartial%5E2%7D%7B%5Cpartial%20y%5Cpartial%20x%7D%282x%2B3y%29%5E%7B10%7D%3D%5Cdfrac%5Cpartial%7B%5Cpartial%20y%7D%5Cleft%5B20%282x%2B3y%29%5E9%5Cright%5D%3D180%282x%2B3y%29%5E8%5Ctimes3%3D540%282x%2B3y%29%5E8)
and in case you meant the other way around, no need to compute that, as
by Schwarz' theorem (the partial derivatives are guaranteed to be continuous because 
is a polynomial).
