Question

What is the axis of symmetry of h(x) = –2x2 + 12x – 3?

x = –15
x = –3
x = 3
x = 15

Answer 1

`the axis of symmetry is the x value of the vertex`
`we have a handy-dandy way of finding that from standard form, ax^2+bx+c=y`

`for`
`ax^2+bx+c=y`
`the x value of the vertex is -b/2a`

`y=-2x^2+12x-3`
`-b/2a=-12/(2*-2)=-12/-4=3`

`x=3 is the axis of symmetry`
