Question

Help me smoeone please


What is the inverse equation of the function, y = 3x - 6?

Answer 1

if multiplicative inverse then 1/3x-6
or additive Inverse theme -3x+6

Answer 2

Given function
f
(
x
)
=
3
x
−
6
, then
f
−
1
(
x
)
⇒
x
=
3
y
−
6
We must isolate the
y
in
f
−
1
(
x
)
to get the proper form of the inverse.
x
=
3
y
−
6

x
+
6
=
3
y

x
3
+
6
3
=
3
y
3

y
=
1
3
x
+
2
f
−
1
(
x
)
=
