The formula is y=ax^2+bx+c
I also gave the wrong problems, they are...
well for number one you said it was
y = -x^2 +1
when you graph it here are three points
(-1,0), (0,1),(1,0) so you know that the parabola is going downward. the axis of symmetry is the line in the middle of the parabola which would be : 0
the vertex point would be: (0,1)
I don't have my book with me but the formula for finding the axis of symmetry should be in your book. I can help you if you send it to me.
IDENTIFY THE AXIS OF SYMMETRY, CREATE A SUITABLE TABLE OF VALUES...
