What a finished MA 109 Unit 4 polynomial functions looks like
Each polynomial gets a short profile rather than a single answer line. The profile opens with the degree and the sign of the leading coefficient, and states in words what the curve does at both far ends. Zeros come next, found with the working shown, and each one is confirmed by substitution rather than accepted from a factoring step. Beside every zero sits its multiplicity and a note saying whether the curve crosses the horizontal axis there or turns back from it. A sign analysis across the intervals between zeros follows as a small table saying where the function sits above the axis and where below. The sketch closes the item, with the zeros marked at their values, the far ends drawn to match the stated behavior, and the vertical scale chosen so turning points stay visible.
How a MA 109 Unit 4 example is structured
End behavior is settled from the degree and leading sign before any zero is hunted, because the two ends of the sketch are decided by that alone and a drawing that contradicts them is wrong before it begins. Zeros are verified by substitution rather than trusted, since a sign error during factoring produces a value that looks plausible and fails silently. Multiplicity is recorded next to each zero rather than mentioned in a paragraph, as it is what tells the sketch whether to cross or to bounce, and that detail is commonly the difference between a correct shape and a near miss. The sign table comes before the sketch because it fixes the curve between the zeros, which is the region a freehand drawing tends to invent. The sketch is drawn last, and it is treated as the summary of everything above it rather than as the answer itself.
End behavior fixed before anything else
Degree and leading sign decide what the curve does at both extremes, and that is settled before a single zero is located.
Every zero confirmed by substitution
A value produced by factoring is put back into the polynomial, because a sign error there yields a plausible zero that fails quietly.
Multiplicity written beside each zero
Whether the curve crosses the axis or turns away from it is recorded at the zero itself rather than in a summary paragraph.
A sign table between the zeros
The intervals between zeros are examined in a short table, which fixes the regions a freehand sketch would otherwise invent.
The sketch drawn last as summary
Nothing new appears in the drawing; it restates the degree, the zeros, the multiplicities and the ends that the profile already established.
Where marks go in MA 109 Unit 4
Sketches that contradict the profile above them are the signature loss in this unit. A curve drawn with both ends rising over a polynomial of odd degree tells a marker the end behavior section was written and then ignored. Zeros listed without multiplicity leave the shape undetermined at every one of them. A factored form presented as the answer, with the zeros never extracted, stops a step short of what was asked. Polynomials divided with no remainder stated, where the division was the point, lose the result the item wanted. Sketches with unlabeled axes cannot be checked against the zeros that were computed. Turning points drawn at values nothing supports are invention rather than analysis. A graph produced by software and pasted in, with the zeros neither found nor verified, leaves the unit's actual work undone.

MA 109 Unit 4 questions, answered
How precise does the sketch need to be?
Accurate at the points that were computed and honest everywhere else. Zeros belong at their values on a labeled axis, the ends have to match the behavior you stated, and the curve between zeros has to stay on the side the sign table gives it. Turning points are normally not required to be exact in this course unless the instructions ask, and guessing at them precisely is worse than drawing them approximately.
The item lists several polynomials. Does every one need the full profile?
Read the instructions on that point, because sections divide it differently. Where a uniform profile is requested, each polynomial gets the same treatment and the consistency itself is worth credit. Where the items ask different things, answer what each one asks and do not pad the rest into the same template, since a marker following the rubric line by line finds the padding before it finds the answer.
Is it a problem if a classmate and I both order an example?
It would be, so we do not let it happen: every example is written from the instructions and rubric that arrive with the request, and two requests on the same unit produce two different pieces of work with different composite figures in them. We also keep what you send private. What your classroom posts is your instructor's material and stays between you and us.
