This assignment addresses concepts and skills that are lightly covered, but should be mastered.

We find the vertex of by finding the point , by computing and directly.

In this Supplementary Exercise, we complete the square, so we are able to write in the form

,

and we simply read the vertex directly from the way we write . I think it's of value to do this both ways.

I don't want you to waste time typesetting this assignment in Word. Just do the work by hand on plain white paper, preferably unruled. You may scan and e-mail or fax your work to me, or mail it to me through regular U.S. Mail.

Graph each of the following by completing the square. Features I expect to see:

a. y–intercept

b. x–intercepts (if any)

c. vertex

d. general "shape" (a smooth parabola)

I also expect to see the work you did in completing the square for each.

Grading Rubric: 5 points each problem y–intercept – 1 point x–intercepts – 1 point Complete the square successfully – 1 point vertex – 1 point general shape of the parabola – 1 point
