Question

Find the equation of the axis of symmetry and the coordinates of the vertex of the graph of the function y = –2x2 +6x – 1

Answer 1

@JoannaBlackwelder

Answer 2

is that,\[y=-2x^2+6x-1\]?

Answer 3

the axis of symmetry is the line that has the x- coordinate of the vertex

Answer 4

the vertex is (h, k) where h = -b/(2a) from the standard form

Answer 5

vertex form of the equation a(x-h)^2 + k = 0

Answer 6

how would you complete the square for the given function?

Answer 7

Yes @RSTONE2017

Answer 8

I don't know how to solve it @triciaal

Answer 9

the red line is the axis of symmetry. the "mirror" of the parabola

Answer 10

from the given equation in standard form identify a, b and c

Answer 11

what is -b/(2 a ) ?

Answer 12

are you here?

Answer 13

yeah but don't know what to do or how to solve :( @triciaal

Answer 14

what is the standard form of a quadratic equation?
