Question 90218This question is from textbook Beginning Algebra
: I need to identify the axis of symmetry, create a suitable table of values and the sketch a graph including the axis of symmetry for y = x^2 - 5x + 3.
I know the formula to find the axis is x = -b/2(a)thus...
x = -(-5)/2(1) = 5/2
From here on out I'm lost. I get really confused when there is a fraction. I don't which values to choose and why to choose them.
Please help.

You can put this solution on YOUR website! you've got the hard part ... for your table of values, choose numbers for x that are equally spaced around the axis of symmetry
like 2, 3, 1, 4, 0, 5 ... then plug these values into the original equation to get matching y values
