Math B/9.1
Two parabolic arches are to be built. An equation of the first arch is given to be y = -x^(2) + 9, with a range of 0 ≤ y ≤ 9. The second arch is created by the transfomation of the vertex (7,0).
(a) Using graph paper, graph the equations of the two arches on the same set of axes.
(b) Graph the line that is symmetric to the parabola and its transformation. Laber the line of symmetry with its equation.
NOTE: I know that yahoo answers does not have a section for graphing equations of any kind. If you could someone provide the steps to do solve this two-part math question, it would help a little bit.

y1 = 9 - x² ----> y2 = 9 - [ x - 7 ] ² , with x = 0 and x = 7 being the lines of symmetry
and note that x = 3.5 is the line of symmetry for y1 vs y2
and note that x = 3.5 is the line of symmetry for y1 vs y2
