Question

Begging for help. Algebra 2. Will fan and medal... PLEASE and thank you!!

1. Draw the graph of the function f(x)= [x]+1 for the domain -2 < x < 2 .

2. consider the function f(x)=2/5x-4.
a.Find the inverse of f(x) and g(x) and name it . Show and explain your work.
b. Use function composition to show that f(x) and g(x) are inverses of each other.

Answer 1

please. You all dont understand i am going through so much. i just need someone to do this so I can catch up.... :(

Answer 2

I'll try my best to help

Answer 3

i'm in middle in class so if i don't do it sorry

thank you!

Answer 5

Here is my answer for number 1. Got it from wolfram Alpha.

Answer 6

you still need help with this?

Answer 7

I do @timanti

Answer 8

f(x)=[x] is called the "greatest integer function." For an explanation of this function, please see

https://www.google.com/search?sourceid=chrome-psyapi2&ion=1&espv=2&es_th=1&ie=UTF-8&q=greatest%20integer%20function&oq=greatest%20integer&aqs=chrome.0.0j69i57j0l4.4072j0j7

Following the examples in this web page, graph the greatest integer function for the open interval -2 < x < 2.

That " +1 " in the given function will move your whole graph downward by 1 unit. This is called "vertical translation."
