Which is the inverse of the function f(x) = 4x2
Sholpan [36]

Answer:

\sqrt{\frac{x}{4}}  and  -\sqrt{\frac{x}{4}}

Step-by-step explanation:

The function is given as  f(x)=4x^2

<em>to find inverse, we follow the steps shown below:</em>

<em>1. write "y" in place of "f(x)"</em>

<em>2. interchange "x" and "y"</em>

<em>3. solve for the new "y"</em>

<em>4. replace y with f^-1(x)</em>

<em />

Let's do this:

f(x)=4x^2\\y=4x^2\\x=4y^2\\y^2=\frac{x}{4}\\y=+-\sqrt{\frac{x}{4}}

These 2 are the inverse functions.

So, the trick question answer is 0% that exactly one is rotten and 100% that All are rotten.
