## What is the inverse of Y 3x?

f-1

Answer: The Inverse of y = 3x is f-1(x) = 1/3x.

**What is the formula in inverse?**

An inverse variation can be represented by the equation xy=k or y=kx . That is, y varies inversely as x if there is some nonzero constant k such that, xy=k or y=kx where x≠0,y≠0 . Suppose y varies inversely as x such that xy=3 or y=3x . That graph of this equation shown.

### How do you find the inverse of a function?

Given the function f(x) we want to find the inverse function, f−1(x) f − 1 ( x ) . First, replace f(x) with y . This is done to make the rest of the process easier. Replace every x with a y and replace every y with an x .

**What is the inverse of y 3x 4?**

The inverse function of 3x – 4 is (x+4)/3.

#### Is the inverse of y 3x 1 a function?

This is a linear relation and therefore a function (all linear relations are functions).

**Which equation is the inverse of Y 2×2 8 quizlet?**

Answer: √[(x + 8) / 2] is the inverse of y = 2×2 – 8.

## How do you find the inverse property?

To find the multiplicative inverse of a number, all you have to do is find the reciprocal of the number. If you have the number 99, the reciprocal is 1/99. This is also the multiplicative inverse because when you multiply 99 and 1/99, you get 1 as a result.

**What is the inverse square law in simple terms?**

Specifically, an inverse square law says that intensity equals the inverse of the square of the distance from the source. For example, the radiation exposure from a point source (with no shielding) gets smaller the farther away it is. If the source is 2x as far away, it’s 1/4 as much exposure.

### How do you tell if a graph is an inverse function?

Let f be a function. If any horizontal line intersects the graph of f more than once, then f does not have an inverse. If no horizontal line intersects the graph of f more than once, then f does have an inverse. The property of having an inverse is very important in mathematics, and it has a name.

**What is the inverse of 7?**

For example, if we have the number 7, the multiplicative inverse, or reciprocal, would be 1/7 because when you multiply 7 and 1/7 together, you get 1!

#### What is the inverse of 2X 7?

Reversing a Function If the original function is f(x)=2x-7, the order for the function is to multiply the x by 2 and then subtract 7. The inverse reverses this, so it adds 7 to the y and then divides by 2. So, the inverse of f(x)=2X-7 is f^-1(y)=(y+7)/2.
