Three functions are given below: f(x), g(x), and h(x). Explain how to find the axis of symmetry for each function, and rank the functions based on their axis of symmetry (from smallest to largest).

AnimeGhoul8863:

f(x)= 3(x + 4)2 + 1 g(x) = 2x2 − 16x + 15

AnimeGhoul8863:

h(x)

Jesus is du answer.

AnimeGhoul8863:

F(x)= Vertex=(-4,1) Axis of symmetry=-4 Directrix=y=11 over 12

AnimeGhoul8863:

G(x)= Vertex=(4,-17) Axis of symmetry=4 Directrix=y=-137 over 8

AnimeGhoul8863:

@dude could you help me out again

AnimeGhoul8863:

Im stuck on h(x)

dude:

Are you stuck on all of h(x)?

AnimeGhoul8863:

h(x)= Vertex or Axis of symmetry = (-3,1) ?

AnimeGhoul8863:

i think like half like i dont know if (-3,1) is the vertex or the Axis of symmetry

dude:

|dw:1540246283778:dw|

AnimeGhoul8863:

i split the graph in to two to find the Axis and i got (-3,1)

dude:

|dw:1540246299449:dw|

AnimeGhoul8863:

ok so (-3,1) is the vertex but im confused on what the axis of symmetry is

dude:

Not quite, points are written as (x,y)

AnimeGhoul8863:

oh ok so (1,-3)

dude:

Yes

AnimeGhoul8863:

would the Axis be 1?

dude:

Yep x=1

AnimeGhoul8863:

e.e Ok ok soooo the answer to this question is

HuskyNation:

when in doubt answer is always B

AnimeGhoul8863:

x'D

AnimeGhoul8863:

f(x)= 3(x + 4)2 + 1 This Equation has a Axis of symmetry of -4 i found this out by Graphing the Equation and splitting the graph into two pieces. g(x) = 2x2 − 16x + 15 This Equation has a Axis of symmetry of 4 i also found this out by graphing the Equation and splitting the graph into two pieces. h(x) This Equation has a Axis of symmetry of 1 i found this out by splitting the graph into two pieces to determine the Axis. The largest Axis would be G(x) = 2x2 − 16x + 15

AnimeGhoul8863:

imma go with what i got Bye bye
