Question

Rank axis from smallest to largest:

1
4
-4

Answer 1

axis of symmetry

Answer 2

my order: 4, 1 , -4
is that right?

Answer 3

Try plotting 1, 4 and -4 on the x-axis. Which comes first? second? third?

Answer 4

You want them

Answer 5

in increasing order of size.

Answer 6

"rank the functions based on their axis of symmetry (from smallest to largest)" this is what the question asks @mathmale

Answer 11

@Directrix any thoughts?

Answer 12

Sorry. I've not heard of ranking functions by axis of symmetry. I need to study.

Answer 13

Go back and check the wording of the original question. I agree with Directrix (above).

Answer 14

>>Try plotting 1, 4 and -4 on the x-axis.

If you follow mathmale's hint, then your answer of >> my order: 4, 1 , -4
is not correct because you have the numbers in decreasing order of size.

Reading the x-axis from left to right, 4 does not come before 1 and 1 does not come before -4.

Answer 15

Yes. Please post the functions associated with the axes of symmetry.

Answer 16

Oh right: so -4 , 1 , 4
@Directrix ?

Answer 17

If the original but unposted functions are parabolas that open upward or downward, then the lines of symmetry x = -4, x = 1, and x = 4 would appear as parallel lines in that order.

If I understand the question, then, yes, I think your answer is now correct.

I can't say that I am certain, though.

Answer 18

well this is the question

Answer 19

These are my answers
The axis of symmetry is simply the x coordinate of the vertex.
g(x), x = -b/(2a) = 16/(2*2) = 16/4 x = 4, the axis of symmetry is 4.
h(x), the vertex is (1, -3). Therefore the axis of symmetry is 1.
f(x), the expression is in vertex form: a(x-h)^2 +k. The variables h and k represent the vertex so (-4, 1) The axis of symmetry is -4.

Answer 20

@Directrix

Answer 21

The problem says to rank the functions based on each one's axis of symmetry from small to large.

Rather than answer with the equations of the axes of symmetry, I think you are to respond with the functions.

f(x), h(x), and g(x)

That order corresponds to the -4, 1, 4 which you mentioned earlier in the post.

Answer 22

Oh alright that sounds just about right, thank you so much !

Answer 23

You are welcome.
