Hello Jack:

We ask that students do not post lists of homework exercises, without asking any questions of their own. Please check out our forum guidelines; here's a link to the summary page. (You'll find links to the complete rules and guidelines appear near the bottom.)

Do you have a textbook? If so, look at the index under "graph" for a section on transformations. If you have any questions about your lessons or notes, those questions are what we need to see.

You're told that symbol f(x) = x^2

Do you know that symbol f(x) is just another name for symbol y.

Therefore, adding some amount a to the y-coordinate of a point shifts the point vertically by a units.

Since every point on the parabola of y=x^2 is shifted a units, the entire graph moves a units (up or down, depending on whether a is positive or negative; of course, the graph does not shift at all, if a=0).

Please explain what you do not understand, about these exercises, so that tutors may determine where to begin helping you.

Thank you! :cool:
