Question

FAN AND MEDAL PLEASE HELP
will attach pic

Answer 1

@phi? can u help i haven't done this stuff in forever

Answer 2

Well the vertex is the highest point.

Answer 3

do you know what the vertex is?

Answer 4

oh sorry but just locate the vertex and find the coordinates

Answer 5

i have no clue i missed a day bc i went and got a puppy and so i know nothing of this

Answer 6

is the vertx just 3, -1?

Answer 7

yup

Answer 8

so how do i find the equation for axis of symmetry

Answer 9

Yes 3, -1 is correct

Answer 10

is there an equation i need to plug that into for the axis of symmetry?

Answer 11

Now for the axis of symmetry any idea?

Answer 12

is it just x = 3 since that's the middle line

Answer 13

Yes the center that cuts the parabola at the vertex in half.

Answer 14

so then a 3, -1 and b x = 3?

Answer 15

No just the 3 because it is only the line that goes straight down.

Answer 16

so the answer is just 3 even though it says write an equation

Answer 17

Find the axis of symmetry of the parabola shown. The x-coordinate of the vertex is the equation of the axis of symmetry of the parabola. The vertex of the parabola is (2, 1). So, the axis of symmetry is the line x = 2

Answer 18

If they want the equation than that is different.

Answer 19

It is a vertical line with the equation of x = -b/2a

Answer 20

If the vertex of a parabola is (k,l), then its axis of symmetry has equation x=k.

Answer 21

We can find a simple formula for the value of k in terms of the coefficients of the quadratic. As usual, we complete the square:

y=ax^2+bx+c

Answer 22

Do you understand?
