The answer is 0 because one there are no more numbers and when you divide -x by 0 you end up with 0

So basically it’s just -0 divided by -0 which is just 0

Find the inverse of f(x) = -4x - 12

olga2289 [7]

Answer:

$\implies f^{-1}(x) =-\dfrac{x}{4}-3$

Step-by-step explanation:

<u>Given </u><u>:</u><u>-</u><u> </u>

f(x) = -4x-12

And we need to find out the Inverse of the function . Let us assume that f(x) = y . Now , firstly replace x with y and vice versa.

<u>Function</u><u> </u><u>:</u><u>-</u><u> </u>

$\implies f(x) = -4x - 12 \\\\\implies y = -4x-12$

<u>Interchanging</u><u> </u><u>x </u><u>and </u><u>y </u><u>:</u><u>-</u><u> </u>

$\implies x = -4y - 12$

<u>Solve </u><u>out</u><u> </u><u>for </u><u>y </u><u>:</u><u>-</u><u> </u>

$\implies x = -4y - 12 \\\\\implies -4y = x +12 \\\\\implies y =\dfrac{x+12}{-4}\\\\\implies y =-\dfrac{x}{4}-3$

<u>Replace</u><u> </u><u>y with</u><u> </u><u>f-¹</u><u>(</u><u>x)</u><u> </u><u>:</u><u>-</u><u> </u>

$\implies f^{-1}(x) =-\dfrac{x}{4}-3$

<u>Hence </u><u>the </u><u>inverse</u><u> of</u><u> the</u><u> function</u><u> is</u><u> </u><u>-x/</u><u>4</u><u>-</u><u>3</u><u> </u><u>.</u>
