Which statement best describes the graph of x3 − 3x2 − 4x 12? it starts down on the left and goes up on the right and intersects the x-axis at x = −2, 2, and 3. it starts down on the left and goes up on the right and intersects the x-axis at x = −2, 4, and 3. it starts up on the left and goes down on the right and intersects the x-axis at x = −2, 2, and 3. it starts up on the left and goes down on the right and intersects the x-axis at x = −2, 4, and 3.

option A is correct.

Step-by-step explanation:

We are given the graph of .

clearly the roots of this equation is:

⇒  ,and are the roots of the equation.

Hence the graph will intersect x-axis at these 3 points x=3,2 and -2.

From the graph we could clearly see that the graph starts down on the left and goes up on the right and intersects the x-axis at x=2,-2 and 3.

Hence, option A is correct.

answer: 7 x 2/5 = 2.8 hours, is your answer. your welcome! : 3

step-by-step explanation: first work out how long it took to hose 1/7 of the lawn which is 2/5 hours. times that by 7 to get the whole lawn.

sorry i don't know the other answer. i didn't learn what a proportional relationship is.
