Question

find $f^{-1}(g(-19))$.

$x$$f(x)$$g(x)$
$10$$10$$9$
$-8$$17$$1$
$-19$$-5$$-17$
$18$$-13$$16$
$-18$$-4$$-5$
$-11$$9$$11$
$-5$$-17$$-19$

Explanation:

Step1: Find \( g(-19) \)

Look at the table for \( g(x) \). When \( x = -19 \), \( g(-19) = -17 \).

Step2: Find \( f^{-1}(-17) \)

We need to find \( x \) such that \( f(x) = -17 \). From the table, when \( f(x) = -17 \), \( x = -5 \) (since \( f(-5) = -17 \)). So \( f^{-1}(-17) = -5 \).

Answer:

\( -5 \)
