Use the key features of the polynomial f(x) = 5x2 − 2x − 3 to describe its end behavior.
a. the left side continues up, and the right side continues down.
b. the left side continues down, and the right side continues down.
c. the left side continues down, and the right side continues up.
d. the left side continues up, and the right side continues up.

d. The left side continues up, and the right side continues up.

Step-by-step explanation:

We have been given a polynomial . We are asked to describe the end behavior of our given polynomial.

We know that for a function of form , if n is even and , then

We know that for a function of form , if n is even and , then

We can see that for our given polynomial the value of 'n' is even and , which is greater than 0. So both sides of our given function continues up.

Therefore, option D is the correct choice.

im sorry but no. i just need to answer for 50 poonts oof

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
