icang [17]

Answer:

Step-by-step explanation:

Turn the question around so it is easier to see.The open end is closest to n.

6n>48 Divide by 6

6n/6>48/6

n > 8

So all you have to do is choose 3 values greater than 8

How about 9,10,11

What is the inverse of this function? f(x)=-1/2 square root of x+3, x > -3

yuradex [85]

The inverse function of $f(x) = -\frac 12\sqrt{x + 3}$ is $f^{-1}(x) = 4x^2- 3$

<h3>How to determine the inverse function?</h3>

The function is given as:

$f(x) = -\frac 12\sqrt{x + 3}$

Rewrite as;

$y = -\frac 12\sqrt{x + 3}$

Swap the positions of x and y

$x = -\frac 12\sqrt{y + 3}$

Multiply through by -2

$-2x = \sqrt{y + 3}$

Square both sides

4x^2 = y + 3

Subtract 3 from both sides

y = 4x^2 - 3

Express as an inverse function

$f^{-1}(x) = 4x^2- 3$

Hence, the inverse function of $f(x) = -\frac 12\sqrt{x + 3}$ is $f^{-1}(x) = 4x^2- 3$
