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.

Triangle ABE is similar to triangle ACD. Find y.

balu736 [363]

ΔABE is similar to ΔACD

AB/AC = AE/AD

.

<u>Solve y:</u>

3/5 = y/(y+ 3)

3(y + 3) = 5y

3y + 9 = 5y

2y = 9

y = 4.5

.

Answer: y = 4.5
