Can someone help with this question? $32,000;7%decrease
Vitek1552 [10]
To find a decrease using a percentage you:

Original Amount - (Original Amount x Percentage)

So plug in:

32000 - (32000 x 7%) = 32000 - (32000 x 0.07) = 29760

The amount with a 7% decrease is $29,760.

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