Find the function !!! 10 points - Help needed!
Arte-miy333 [17]
<h2>Hello!</h2>

The answer is:

The first option,

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

<h2>Why?</h2>

To find the inverse of a function, we need to rewrite the variable "x" with "y" and the variable "y" with "x", and then, isolate "y".

We are given the function:

f(x)=4x+2

Write "f(x)" is equal to write "y", so:

y=4x+2

Now, finding the inverse, we have:

y=4x+2\\x=4y+2\\x-2=4y\\y=\frac{x-2}{4}

Hence, we have that the answer is the first option,

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

Have a nice day!

Find the new price for the markup given. Round to the nearest cent if necessary. $3.00 marked up 72%
Marrrta [24]

Answer:

$5.16

Explanation:

Okay, so the first step is to move the decimal point of the 72% over to the left twice. Since it is a whole number, the decimal is at the back. So, the number went from 72 to .72.

After that, multiply 3.00 by .72 Like this:

3.00 * .72 = 2.16

The last step is to add the original number to that number. Like this:

3.00 + 2.16 = 5.16

Hope this helps !
