The profit of a small business (in thousand dollars) since it was founded can be modeled by the polynomial f(t)=-t4+44t3-612t2+2592t, where t represents the number of years since 2005. What was the business’s profit in 2010? What recommendation can you make for this business in regards to it’s long term prospects? Support your answer with numbers from the graph. USE DESMOS

step-by-step explanation:

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.
