Question

f(x) = 4|x + 1| 6
What is the vertex of the graph of f(x)?
(-1, -6)
(-1, 6)
(1, -6)
(4, -6)

Answer 1

The graph of abs(x-1) is going to be shiftedone unit to the right, so its coordinates is (1,0), so we want 4 times that.

Answer 2

..4,6?

Answer 3

*-6

Answer 4

\(\large f(x) = 4|x + 1|- 6 \)

Answer 5

is the given equation like above ?

there must be a + or - sign before 6. check once

Answer 6

you are right once again lol

Answer 7

so its a minus sign ha

Answer 8

yesss :3

Answer 9

okay :)

so you wanto find vertex of this absolute value function

Answer 10

yessss indeed

Answer 11

to find x coordinate, simply set the thing between BARS to 0

x+1 = 0

x = ?

Answer 12

-1?

Answer 13

yup ! x = -1

you still need to find y

Answer 14

yeah that was my problem... i dont know how to find y

Answer 15

y is simply the thing outside BARS

Answer 16

oh! so negitive 6?

Answer 17

\(\large f(x) = 4|x + 1|- 6\)
^^^^

Answer 18

yup !

Answer 19

x = -1
y = -6

Answer 20

:)) thank u so much.. i dont understand how to do algebra much because i do k12 and its independent work :c

Answer 21

so i kinda have to teach myself this stuff

Answer 22

oh nice, you're doing a great job ramping up on ur own ! keep it up !!

Answer 23
