Answer: Question 1 :B,D.

Question 2:option B,

Question 3:Degree=5.

Question 4:option D.

Question 5: option c.


Step-by-step explanation:

1) A polynomial can not have any exponent as a variable or a fraction.

Options B and D are polynomials.

2) The polynomial is having 3 terms and is of degree 3.so it is a cubic trinomial Option B.

3) Degree is the highest power of the variables in the terms .The term 6x^{3} y^{2} has the power=3+2=5

So degree =5.

4)(5x-2+3x^{2} )+(4x+3)=3x^{2} +5x+4x-2+3=3x^{2}+9x+1.

Option D


5)(5x^{2} +2x-5)-(3x^{2}+3x+1)= 5x^{2}+2x-5-3 x^{2}-3x-1

Simplifying like terms,

=2x^{2}-x-6.

Option c.

PLEASEEEEE HELLPPP!!!
Veseljchak [2.6K]

Answer:

4

Step-by-step explanation:

f(x) (8x² - 3x + 1) / (2x² + 2x +3)

the first thing I did was to graph the function to see if there was a horizonal asymptote using Desmos graphing calculator and there was and it was 4

you want to take the limit as x approaches infinity

essentially  lim(x to ∞) of f(x) = 8x²/ 2x²      is the dominate terms

                    lim(x to ∞) of f(x) = 8 / 2

                    lim(x to ∞) of f(x) = 4
