Answer:

$f^{-1}(x) = \frac{1}{2}(x +4)$

Step-by-step explanation:

Given

$f(x) = 2x - 4$

Required

Determine the inverse function

Start by replacing f(x) with y

$y = 2x - 4$

Swap the positions of y and x

$x = 2y - 4$

Make y the subject: Add 4 to both sides

$x+4 = 2y - 4+4$

$x+4 = 2y$

Make y the subject: Divide through by 2

$\frac{1}{2}(x + 4) = y$

$y = \frac{1}{2}(x + 4)$

Replace y with f-1(x)

$f^{-1}(x) = \frac{1}{2}(x +4)$

Please help this is due tmrw

Sorry, I only know 8, 9, and 10.

8. This can be anything, but my guess would be 40 - 20 = 20
9. 3, because 3 x 3 = 9.
10. 7, because 7 x 4 = 28.

Hope this helped!

We will have the following:

*It will have a domain of x equal or greater than 0:

$x\ge0$

It will have a domain of y equal or greater than 0:

$y\ge0$

***

We have the following:

We determine the domain as follows:

Since the function is subject to a root, no negative value can be put in it, so its domain (Since x is not accompanied by any value in the root) can only "hold" values equal or greater than 0.

We determine the range as follows:

Since the function is subject to a root, it's solutions will never be negative, so its range can only hold values equal or greater than 0.
