Question

f(x)=mx+c
why does an inverse function not exist if m=0

Answer 1

i understand how g(x)=y/0 -c/0

Answer 2

Well let m=0
f(x)=0*x+c =0+c=c
So then f(x)=c

Answer 3

Fine lets do it like that
y=0*x+C

Now lets fine the inverse:
\[x=0*y+c\]
\[y=\frac{x-c}{0}\]

Answer 4

inverse is not define because it give infinity when m=0.

Answer 5

@Maretch Do you understand?
