Question 80077: Can someone help me please I do not understand this any portion of it can someone help me please? identify the axis of symmetry, create a suitable table of values, and sketch the graph (including the axis of symmetry).
y=x^2-5x+3

identify the axis of symmetry, create a suitable table of values, and sketch the graph (including the axis of symmetry).
y=x^2-5x+3
-------------
One way to accomplish this is to find the x-coordinate of the vertex:
x=-b/2a= -(-5)/2=5/2
That is the axis of symmetry.
----------
To create the "table" let x have a few values and solve for y:
If x=0, y=3
If x=1, y=-1
If x=2, y=4-10+3=-3
If x=3, y=9-15+3=-3
If x=4, y=16-20+3=-1
------------
