Graph of a cubic polynomial that falls to the left and rises to the right with x intercepts negative 2, negative 1, and 2
Which of the following functions best represents the graph? (4 points)

a
f(x) = x3 + x2 − 4x − 4

b
f(x) = x3 + 4x2 − x − 4

c
f(x) = x3 + 3x2 − 4x − 12

d
f(x) = x3 + 2x2 − 4x − 8

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.

the answer to this in exact form is 4/35 but in decimal form its 0.1142857
