Find the inverse of each function. Is the inverse a function? y=(x+4)³-1

tatuchka [14]

Inverse of the give function F(x) = ( x + 4 )³ - 1 is F⁻¹(x) = [√( x + 1 ) ] - 4.

Given is a function of x, F(x) = ( x + 4 )³ - 1

These question can be solved by following 4 easy steps

Step 1 : Switch the F(x) with the variable y

This implies, F(x) = ( x + 4 )³ - 1 becomes y = ( x + 4 )³ - 1

Step 2 : Interchange the variable x and y in the above obtained equation

This implies, from the equation y = ( x + 4 )³ - 1, we get

x = ( y + 4 )³ - 1

Step 3 : Solve the new obtained equation for y

This implies, we have to simplify the equation by rearranging the terms to get the equation in terms of the variable x.

x = ( y + 4 )³ - 1

=> x + 1 = ( y + 4 )³

=> (y + 4 )³ = x + 1

=> y + 4 = √( x + 1 )

=> y = √( x + 1 ) - 4

Hence we obtain the required equation.

Step 4 : Switch the variable y with F⁻¹(x)

This implies, y = √( x + 1 ) - 4 becomes F⁻¹(x) = √( x + 1 ) - 4

Therefore, we get the inverse of the give function F(x) = ( x + 4 )³ - 1 as F⁻¹(x) = [√( x + 1 ) ] - 4.

Determine the inequality that can be used to model when the population of bacteria will be greater than or equal to 656,100. The

jenyasd209 [6]

The inequality is 100* $3^{t}$ ≤ 656100.

The correct option is (B).

<h3>What is inequality?</h3>

A statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions.

Given:

From the table attached below:

a=300, r= 900/300 = 3

As, it is GP

Now,

f(t) = $ar^{t-1}$

f(t) = $300*3^{t-1}$

f(t) = 300/3 * $3^{t}$

f(t) = 100* $3^{t}$

Inequality is used to determine greater than or equal to 656100

100* $3^{t}$ ≤ 656100

Please answerrrr Graph g(x), where f(x) = 4x − 2 and g(x) = f(x + 1). a line labeled g of x that passes through points 0, negati

Mrrafil [7]

Answer:

a line labeled g of x that passes through points negative 1, negative 2 and 0, 2

Step-by-step explanation:

we have

$f(x)=4x-2$

$g(x)=f(x+1)$

To determine g(x), substitute the variable x by (x+1) in the function f(x)

$f(x+1)=4(x+1)-2$

$f(x+1)=4x+4-2$

$f(x+1)=4x+2$

$g(x)=f(x+1)$

$g(x)=4x+2$

therefore

a line labeled g of x that passes through points negative 1, negative 2 and 0, 2
