What is the inverse of the function f(x) = x 3? h(x) = one-thirdx 3 h(x) = one-thirdx – 3 h(x) = x – 3 h(x) = x 3
riadik2000 [5.3K]

The inverse of the function f(x) = x^{3} is : \sqrt[3]{x}

<h3 /><h3>What is the inverse of a function?</h3>

The inverse of a function is that function that acts to undo a given function.

Analysis:

if f(x) = x^{3}, then let y = x^{3}

\sqrt[3]{y} = \sqrt[3]{x^{3} }

x = \sqrt[3]{y}

Replace y with x

h(x) = \sqrt[3]{x}

in conclusion, the inverse of h(x) = \sqrt[3]{x}

3 − 1 = 5 + 10 = −5 1/2 Check whether the given value of is a solution to the equation. Justify your answer.
andrey2020 [161]

Answer:

x = -5\frac{1}{2} is the solution

Step-by-step explanation:

Given

3x - 1 = 5x + 10 --- Correct expression

x = -5\frac{1}{2}

Required

Determine if the given solution is correct

To do this, we simply solve for x in the given equation.

So, we have:

3x - 1 = 5x + 10

Collect like terms

3x - 5x = 1 + 10

-2x = 11

Divide both sides by -2

\frac{-2x}{-2} = \frac{11}{-2}

x = -\frac{11}{2}

x = -5\frac{1}{2}

In the diagram, △ABC≅△DEF. Find the values of x and y.
Scorpion4ik [409]

9514 1404 393

Answer:

  • x = 5
  • y = 20

Step-by-step explanation:

We need x first.

  AB = DE

  12 = 3x -3

  4 = x -1 . . . . . divide by 3

  5 = x

Now, we can find y.

  ∠C = ∠F

  7x +y = 55

  y = 55 -7x = 55 -7(5)

  y = 20

How do you do prime factorization. i still dont get it.
Juliette [100K]
Prime factorization is simply making a number become simplified in the smallest term it can be in. For example 9 Can be broken down into 3 times 3. Your prime numbers are 2, 3, 5, 7, 11, 13, 17,19 because nothing times something will give you that number besides itself and 1
