Do u mean what is f(8)?

(X) = 2x + 5
Inverse = (x-5)/2

F(x) = (x-5)/2
F(8) = (8-5)/2
= 3/2 = 1.5

I need to use Multi-Step function inverse to find the following:

dexar [7]

<u>Answer</u>:

$f^{-1}(x) = \sqrt[5]{\frac{x+7}{9} -10}$

<u>Explanation</u>:

given : f(x) = 9( $x^5$ + 10 ) - 7

replace x and y with each other.

x = 9( $y^5$ + 10 ) - 7

solve for y

x + 7 = 9( $y^5$ + 10 )

( $y^5$ + 10 ) = $\frac{x + 7}{9}$
$y^5$ + 10 = $\frac{x + 7}{9}$

$y^5$ = $\frac{x + 7}{9}$ - 10

y = $\sqrt[5]{\frac{x+7}{9} -10}$

Therefore,

$f^{-1}(x) = \sqrt[5]{\frac{x+7}{9} -10}$
