The graph of the function f(x) = (x – 4)(x + 1) is shown below.
Which statement about the function is true
O The function is increasing for all real values of x
where
x < 0.
O The function is increasing for all real values of x
where
X<-1 and where x > 4.
O The function is decreasing for all real values of x
where
-1 < x <4
O The function is decreasing for all real values of x
where
x < 1.5.

answer: b)

step-by-step explanation:

its a dot plot because since the score is not high numbers.

- both graphs increase on their domain.

- the graphs of both functions have the same x-intercept.

- neither graph has a y-intercept.

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.
