Find the inverse of the given function. f(x)= -1/2*square root of (x+1), x greater than equal to -3

1. First, you must change for . Then, you need to switch and and solve for , as following:

2. Therefore, you have:

The answer is:

Answer

f⁻¹(x) = 4x² - 1

f⁻¹(x) ≥ 35

Explanation

The function to find the inverse for is;

f(x) = -1/2 × √(x-1), x ≥ -3

First equat the function to y the make x the subject of the formula.

y = -1/2 × √(x-1)

Square both sides of the equation

y² = 1/4 ×(x+1)

Multiplying both sides by 4

4y² = x+1

Subtracting 1 from both sides.

x = 4y² - 1

Now interchange x and y.

y = 4x² - 1

The inverse of f(x) = 1/2 × √(x-1) is;

f⁻¹(x) = 4x² - 1 , x ≥ -3

f⁻¹(x) = 4×(-3)² -1

= (4×9) - 1

=36 - 1

=35

Answer,

f⁻¹(x) ≥ 35

the dimensions are:

step-by-step explanation:

we want to find the dimensions of a rectangular box with volume of

we factor to obtain;

we rewrite the rightmost factor to obtain;

recall that:

we apply difference of two squares formula to obtain;

hence the dimensions are
