#

first see where it intersect x and yaxis

#

then find its maxima and minima

#

and check where it is increasing or decrasing

#

@static cove

#

try to find these three things

static cove Jan 9, 2024, 1:23 AM

#

Ok

#

im kind of stuck

#

i plugged in 0 for x and now i have to do (3/2)^-2

gilded phoenix Jan 9, 2024, 1:27 AM

#

where

gilded phoenix Jan 9, 2024, 1:28 AM

#

static cove i plugged in 0 for x and now i have to do (3/2)^-2

so it becomes (2/3)^2

#

= 4/9

static cove Jan 9, 2024, 1:28 AM

#

oh ok

#

i wasnt sure how to make the exponent positive

#

so thanks

gilded phoenix Jan 9, 2024, 1:28 AM

#

ok

static cove Jan 9, 2024, 1:29 AM

#

y=10/9 ?

gilded phoenix Jan 9, 2024, 1:30 AM

#

i think its 14/9

#

2 - 4/9

static cove Jan 9, 2024, 1:30 AM

#

oh

#

oh i see where i messed up

#

now ill find x

#

is this equation right? -2=-1•(3/2)^(-4/9)

#

oh nevermind

#

for some reason i plugged in y for x

#

ill try it again

#

ok so now i have 2=(3/2)^(x-2) is that correct?

gilded phoenix Jan 9, 2024, 1:38 AM

#

for y = 0?

#

its correct

static cove Jan 9, 2024, 1:39 AM

#

ok good

#

im not sure what to do with 3/2^(x-2)

gilded phoenix Jan 9, 2024, 1:39 AM

#

just take power 2/3 on both sides

static cove Jan 9, 2024, 1:40 AM

#

?

gilded phoenix Jan 9, 2024, 1:40 AM

#

$x - 2 = \sqrt[2/3]{2}$

#

I dont think ive learned that yet

#

i will look at the answer key to see what they did

gilded phoenix Jan 9, 2024, 1:42 AM

#

no need to solve this

#

just leave this here

static cove Jan 9, 2024, 1:42 AM

#

yeah but on the test i wouldnt be able to come up with that

gilded phoenix Jan 9, 2024, 1:42 AM

#

ok

static cove Jan 9, 2024, 1:42 AM

#

ill show you the answer key

gilded phoenix Jan 9, 2024, 1:42 AM

#

but you have to plot the graph

static cove Jan 9, 2024, 1:43 AM

#

#

they plotted it on the right

#

but i have no idea how

gilded phoenix Jan 9, 2024, 1:44 AM

#

they made it right

#

if you take the derivative

#

it will be zero as x = -infinity

#

and is a decreasing curve

static cove Jan 9, 2024, 1:45 AM

#

it looks like they only plotted 2 points

#

i feel like im doing more than i need to

#

since i know the asymptote is 2

#

i can estimate

gilded phoenix Jan 9, 2024, 1:45 AM

#

actually we need everything

gilded phoenix Jan 9, 2024, 1:46 AM

#

static cove since i know the asymptote is 2

you can

static cove Jan 9, 2024, 1:46 AM

#

can what? estimate?

gilded phoenix Jan 9, 2024, 1:46 AM

#

but i will prefer to use derivatives

static cove Jan 9, 2024, 1:46 AM

#

what are those

gilded phoenix Jan 9, 2024, 1:46 AM

#

nvm

#

dont youknow differentiation

static cove Jan 9, 2024, 1:47 AM

#

no i never learned that

gilded phoenix Jan 9, 2024, 1:47 AM

#

then its surprising they are gving you functions to plot

static cove Jan 9, 2024, 1:48 AM

#

my teacher isnt very good

#

i pretty much have to learn everything outside of school

#

im going to try to find a server where i can go in a vc with someone so they can walk me through it

#

cause this is still all very confusing to me

#

but thanks a lot for the help

#

.solved
