Question

Need help with functions. I dont need you to do it for me i just need to be walked through it please.

Answer 1

2. Create your own function to teach the Martians about functions. Your function must contain at least two different operations.
3.Using complete sentences, prove to Splott and Fizzle that your function is a legitimate function.
4.Using your function, explain to the Martians how to solve for f(3). Show your work and explain each step using complete sentences.
5.Using complete sentences, describe to the Martians how to find the inverse of your function.

Answer 2

6.The Martians ask you to explain one last thing, Ultimate Math Ambassador. They ask you to create a new function, h(x). Then assign any number to x. Using complete sentences, explain whether f(h(x)) and h(f(x)) will always result in the same number. You will use the function f(x) that you created in problem number 2.

Answer 5

so a function is a series of operations right? you wanna have an addition or subtraction multiplication or division in there

Answer 6

property of a function must be that it must past a vertical line test

Answer 7

So is this right?
F(x)equals 3x+10

Answer 8

some keys dont work sorry

Answer 9

how do you prove to the martian that this is a real function tho??

Answer 10

um.. im not sure

Answer 11

VERTICAL LINE TEST !!! =D

Answer 12

oh right lol i remeber okay.. how do i do that again lol

Answer 13

rise run?

Answer 14

couple of ways to do it but mainly you can first graph the function

Answer 15

then show to the martian that there is no two y values for the same x value

Answer 16

how exactly? sorry im not really sure what to do.. i dont have an actually graph

Answer 17

so sorry for bad drawing but pretend my points pass through 10 on y axis and -10/3 axis

Answer 18

-10/3 on x axis

Answer 19

so i should put something like f(x) equals 3x+10 is a function because it passed the vertical line test?

Answer 20

essentially yes

Answer 21

How would i explain that though?

Answer 22

you know what would be a nice example?

Answer 23

y=x^2

Answer 24

What?

Answer 25

which you can counter with x=y^2

Answer 26

So i should use that?

Answer 27

I think your teacher or who ever is teaching might like it

Answer 28

I MAY BE WRONG lol

Answer 29

its fine... anything hels because i would have no idea what to do
