Q.
What is the inverse of the function
\newline
f
(
x
)
=
−
6
x
−
7
f(x) = -6x - 7
f
(
x
)
=
−
6
x
−
7
?
\newline
f
−

(
x
)
=
f^{-1}(x) =
f
−

(
x
)
=
Replace
f
(
x
)
f(x)
f
(
x
)
with
y
y
y
:
To find the inverse of the function
f
(
x
)
=
−
6
x
−
7
f(x) = -6x - 7
f
(
x
)
=
−
6
x
−
7
, we first replace
f
(
x
)
f(x)
f
(
x
)
with
y
y
y
. So, we have
y
=
−
6
x
−
7
y = -6x - 7
y
=
−
6
x
−
7
.
Swap
x
x
x
and
y
y
y
:
Next, we swap
x
x
x
and
y
y
y
to find the inverse. This gives us
x
=
−
6
y
−
7
x = -6y - 7
x
=
−
6
y
−
7
.
Solve for y:
Now, we solve for y. We start by adding
7
7
7
to both sides of the equation to isolate the term with
y
y
y
. This gives us
x
+
7
=
−
6
y
x + 7 = -6y
x
+
7
=
−
6
y
.
Divide both sides by
−
6
-6
−
6
:
Next, we divide both sides of the equation by
−
6
-6
−
6
to solve for
y
y
y
. This gives us
y
=
x
+
7
−
6
y = \frac{x + 7}{-6}
y
=
−
6
x
+
7
.
Write the inverse function:
The inverse function is then written as
f
−
1
(
x
)
=
x
+
7
−
6
f^{-1}(x) = \frac{x + 7}{-6}
f
−
1
(
x
)
=
−
6
x
+
7
.
