Question

What's the inverse function of f(x) = x - 5?

Answer 1

i think y=3

Answer 2

Show work on how you know it's the inverse.

Answer 3

y= -3
replace y with x we get
x = -3
this is the inverse

Answer 4

that's what I put is there any work to show for it

Answer 5

i think this work is enough which i did but i can do a graphical work for you

Answer 6

like graphical meaning work it on a graph

Answer 7

yes like if we gave a graph and its inverse they will always be symmetrical to the line y=x

Answer 8

*have

Answer 9

thus y = -3 and x = -3 are symmetrical to y = x

Answer 10

I changed the question, so now it's f(x) = x - 5?

Answer 11

@rizwan_uet think you help on this one

Answer 12

f(x) = x - 5
y = x - 5
replace x with y and y with x
x = y- 5
writting it in terms of y we get
y = x+5
this is the required inverse

Answer 13

can work be shown

Answer 14

thats the work above

Answer 15

so it's y = x - 5 & y = x + 5

Answer 16

yes

Answer 17

so there's really not much work you can show when working with inverse functions

Answer 18

ofcourse its a few steps work

Answer 19

can you show them to me

Answer 20

com on please i showed the work to you. look it again
f(x) = x - 5
y = x - 5
replace x with y and y with x
x = y- 5
writting it in terms of x we get
y = x+5
this is the required inverse

Answer 21

I am sorry

Answer 22

What would the inverse be of 2x + 3 all over 6
