Question 92099: I am totally lost and need some help on theses problems
For each eqaution identify the axis of symmetry, creat a suitable table of value and sketch a gragh
Y=X^2-5x+3
and also Y=X^2+6x-2
Thanks a million

identify the axis of symmetry, create a suitable table of value and sketch a gragh
Y=X^2-5x+3
To determine the axis of symmetry you need to complete the square on the x-terms, as follows:
x^2-5x+(5/2)^2 = y-3+(5/2)^2
Factor to get:
(x-(5/2))^2 = y+(13/4)
-------------
The axis of symmetry is x=5/2

=================================
and also Y=X^2+6x-2
x^2+6x+9 = y+2+9
(x+3)^2 = y+11
x=-3 is the axis of symmetry.

=========================
