f(x)=3x 3 inverse function

Answers

Step-by-step explanation:

if I understand this correctly than you are looking for the inverse function of f(x) = y = 3x³.

the inverse function simply tries to calculate the original x it of the original y.

and then, to make it a formal function, we rename x to y and y to x.

y = 3x³

x³ = y/3

[tex]x = \sqrt[3]{ \frac{y}{3} } [/tex]

=> as "regular" function

[tex]y = {f}^{ - 1} (x)= \sqrt[3]{ \frac{x}{3} } [/tex]

For how many days is the total cost $300? ___days

Initial Value 8
Rate of Change 15

Answers

Answer:

≈ 19.5 days

Step-by-step explanation:

Initial Value b = 8 Rate of Change m = 15

Equation of the line:

y = 15x + 8

Find x when y = 300:

15x + 8 = 30015x = 300 - 815x = 292x = 292/15x ≈ 19.5 days

b=initial value=8m=rate if change(Slope)=15

Equate

[tex]\\ \sf\longmapsto y=mx+b[/tex]

[tex]\\ \sf\longmapsto 300=15x+8[/tex]

[tex]\\ \sf\longmapsto 300-8=15x[/tex]

[tex]\\ \sf\longmapsto 292=15x[/tex]

[tex]\\ \sf\longmapsto x=\dfrac{292}{15}[/tex]

[tex]\\ \sf\longmapsto x=19.5[/tex]

Mixed numbers 204/5=

Answers

Answer:

Step 1 - Find Whole Number

Calculate out how many times the denominator goes into the numerator. To do that, divide 204 by 5 and keep only what is to the left of the decimal point:

204 / 5 = 40.8000 = 40

Step 2 - Find New Numerator

Multiply the answer from Step 1 by the denominator and deduct that from the original numerator.

204 - (5 x 40) = 4

Step 3 - Get Solution

Keep the original denominator and use the answers from Step 1 and Step 2 to get the answer. 204/5 as a mixed number is:

204/5 as a mixed number is not the only problem we solved. Go here to convert another improper fraction to a mixed number.

What is 204/6 as a Mixed Number?

Here is the next improper fraction on our list that we converted to a mixed number.

Terminology & Explanation

204 above the division line is called the numerator and 5 below the divison line is called the denominator.

We call the line that separates 204 and 5 the division line. It is also known as the fraction bar or vinculum.

204/5 is an improper fraction because the numerator is greater than the denominator.

A mixed number is an integer (whole number) and a proper fraction.

Find the value of f(3) y=f(x)

Answers

9514 1404 393

Answer:

-4

Step-by-step explanation:

On a graph like this where not every grid line is marked with its value, you have to determine the spacing of the grid lines by noting how many are between the values shown. Here, the vertical grid lines are marked on the x-axis with even numbers on every other line. That means the lines not numbered have a value halfway between the values on the lines that are numbered.

The grid line for x = -3 is the one halfway between the grid lines for -2 and -4. Following that line down to where it intersects the function graph, we find the y-coordinate of that (vertex) point to be -4. (It is on a marked horizontal grid line, so you can read the value from the axis scale.)

The value of f(-3) is -4.

The area of the rectangle will be 4350 Inches squared.

What is the area of the rectangle?

The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the rectangle in a two-dimensional plane is called the area of the rectangle.

Given that a rectangular floor is 7-3" long and 4-2” wide. Here 7 ft 3 in = 87 in. 4ft 2 in = 50 in.

The area of the rectangle is calculated by using the formula below:-

Area = Length x Width

Area = 87 x 50

Area = 4350 Inches

Therefore, the area of the rectangle will be 4350 Inches squared.

What is the absolute value function?

a. y= 7 |x+8| -4

b. y= -7 |x-8| +4

c. y= -7 |x+8| -4

d. y= -7 | x-8| -4

PLEASE HELP PLEASE PLEASE PLEASE

Answers

Answer:

Step-by-step explanation:

The absolute value function would be;

b. y= -7 |x - 8| +4

Given that;

The functions are,

a. y= 7 |x+8| -4

b. y= -7 |x-8| +4

c. y= -7 |x+8| -4

d. y= -7 | x-8| -4

Since, The absolute value function is a mathematical function that returns the positive magnitude or value of a given number, disregarding its sign. It is denoted by enclosing the number within vertical bars (| |).

In the given options, the equation that represents the absolute value function is:

b. y = -7 |x - 8| + 4

This equation represents a downward-opening V-shaped graph with its vertex at (8, 4).

As x approaches 8 from the left, the value of y decreases.

As x moves away from 8 towards positive or negative infinity, the value of y increases.

Therefore, the correct option is (b).
