8 0

First we expand by distributing sum groups
X(x^2 + 2x + 4 ) - 2 (x^2 + 2x + 4)
Then you expand by distributing terms
X^3 + 2 x^2 + 4x - 2 ( x^2 + 2x + 4)
Collect like terms
X^3 + (2x^2 - 2x^2) + (4x - 4x) - 8
Simplify
X^3 - 8

If f(x) = 5x, what is f -1 (x) ?

Gala2k [10]

Answer:

$f^{-1}(x) = \frac{x}{5}$

Step-by-step explanation:

$f^{-1}\left( x\right) =y\Longleftrightarrow f\left( y\right) =x$

…………………………

f(y) = x

⇔ 5y = x

$\Longleftrightarrow y =\frac{x}{5}$

$\Longleftrightarrow f^{-1}(x) = \frac{x}{5}$
