Question

Brett has determined a function f(x) that shows the exponential growth of the number of shoes Larae owns each year. Explain how the f−1(x) can be found and what f−1(132) means.

Answer 1

@Preetha

Answer 2

@Hero

Answer 3

In order to solve this, we need \(f(x)\) since \(f^{-1}(x)\) has to be found.

Answer 4

Did they provide you with \(f(x)\)?

Answer 5

f^-1(132)?

Answer 6

It says "Brett determined a function \(f(x)\)". We need that in order to solve this. \(f^{-1}(132)\) means nothing by itself.

Answer 7

how can f^-1(x) be found?

Answer 8

Provide, the function \(f(x)\), then I'll be able to explain to you how to find it.

Answer 9

there isnt one, thats the whole question is what i typed

Answer 10

Provide the diagram that goes with it.

Answer 11

@Hero there isnt a diagram...

Answer 12

its a short response question..

Answer 13

could f(365) since its one year?

Answer 14

my teacher said "think of what function is the inverse of the exponential functions"

Answer 15

@Hero

Answer 16

thats everything i can provide, thats the whole question...

if you dont know,i have another that i need help with if you have more time

Answer 17

"Number of shoes Larae owns each year"...that's a huge indication that a graph has been provided.

Answer 18

I can't help you with any questions if you don't provide all of the information necessary to understand the questions.

Answer 19

that is all the info provided, can you help with another ?

Answer 20

Phillip received 75 points on a project for school. He can make changes and receive two-tenths of the missing points back. He can make corrections as many times as he wants. Create the formula for the sum of this geometric series, and explain your steps in solving for the maximum grade Phillip can receive. Identify this as converging or diverging.

Answer 21

120% of 75, or 75×1.2
which is 90.
i think

Answer 22

@Hero is this correct? :/

Answer 23

@Australopithecus can you help me please? :/

Answer 24

Alright f^-1(x) is the inverse function, watch this guys video he is really great at explaining this stuff.

theory

How to actually do it,

Answer 25

You should be able to answer this question after watching these videos

Answer 26

i watched that video haha, im honestly so lost in the question..

Answer 27

@Australopithecus, the question he posted originally cannot be solved. The only meaningful information given was \(f^{-1}(132)\) which is actually meaningless by itself.

Answer 28

i dont think it needs to be solved,itr just asks what it means

Answer 29

it is the year in which she has 132 shoes
that is all

Answer 30

doesnt seem logical to ask that tho, i dont know...

Answer 31

@Hero All he needs to know for this question is the theory, he can give a general answer if he understands what an inverse function is
