f(x)=3x+1
f⁻¹(x)=
(x-1)/(3)

f⁻¹(10)=
just subsitute 10 for x in that equaiton
f⁻¹(10)=
(10-1)/(3)
f⁻¹(10)=
(9)/(3)
f⁻¹(10)=3

orderd pari is (10,3)

The ordered pair of
\( f^(-1)(10) \) is
\((10, 3)\).

The notation
\( f^(-1)(x) \) represents the inverse function of
\( f(x) \). If
\( f(x) = 3x + 1 \), then to find
\( f^(-1)(x) \), you switch x and y and solve for y :


\[ x = 3y + 1 \]

Now, solve for \( y \):


\[ 3y = x - 1 \]


\[ y = (x - 1)/(3) \]

So,
\( f^(-1)(x) = (x - 1)/(3) \).

Now, to find
\( f^(-1)(10) \), substitute
\( x = 10 \) into
\( f^(-1)(x) \):


\[ f^(-1)(10) = (10 - 1)/(3) = (9)/(3) = 3 \]

Therefore, the ordered pair of
\( f^(-1)(10) \) is \((10, 3)\).
