What is the equation of this graph

y = (1/2)(x + 4)(x + 1)(x - 3)

Step-by-step explanation:

Since this graph begins in Quadrant III and continues growing in Quadrant I, and has three roots/zeros, we know immediately that it's a cubing function and can confidently write out

y = d(x - a)(x - b)(x - c) as one general form of the cubing function.

In this particular case we have:

y = d(x + 4)(x + 1)(x - 3)  (where the '4' comes from the x-intercept (-4, 0) )

From the graph we know that y = -6 when x = 0, and therefore:

-6 = d(0 + 4)(0 + 1)(0 - 3), or -6 = d(-12), leading to d = 1/2

Then our tentative equation (above) becomes y = (1/2)(x + 4)(x + 1)(x - 3)

do you have the measurements?

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
