Write function as
y
y
y
:
To find the inverse function, we first write the function as
y
=
x
1
5
+
5
7
y = \frac{x^{\frac{1}{5}}+5}{7}
y
=
7
x
5
1
+
5
.
Swap x and y:
Next, we swap x and y to find the inverse function:
x
=
y
1
5
+
5
7
.
x = \frac{y^{\frac{1}{5}}+5}{7}.
x
=
7
y
5
1
+
5
.
Solve for y:
Now, we solve for y. Multiply both sides by
7
7
7
to get rid of the denominator:
7
x
=
y
(
1
/
5
)
+
5
7x = y^{(1/5)}+5
7
x
=
y
(
1/5
)
+
5
.
Isolate term with y:
Subtract
5
5
5
from both sides to isolate the term with
y
y
y
:
7
x
−
5
=
y
1
/
5
7x - 5 = y^{1/5}
7
x
−
5
=
y
1/5
.
Eliminate fifth root:
Raise both sides to the power of
5
5
5
to eliminate the fifth root:
(
7
x
−
5
)
5
=
y
(7x - 5)^5 = y
(
7
x
−
5
)
5
=
y
.
Find inverse function:
We have found the inverse function:
f
−
1
(
x
)
=
(
7
x
−
5
)
5
f^{-1}(x) = (7x - 5)^5
f

=
