What is the inverse of the given relation y 3x 9?, You can find the inverse by switching the x and y. Then solve for y. x = 3y + 9 (subtract 9 from both sides)…. x – 9 = 3y (now divide each side by 3)…..
Furthermore, What is the inverse of the given function?, In simple words, the inverse function is obtained by swapping the (x, y) of the original function to (y, x). We use the symbol f − 1 to denote an inverse function. For example, if f (x) and g (x) are inverses of each other, then we can symbolically represent this statement as: g(x) = f − 1(x) or f(x) = g−1(x)
Finally, What is the zero of Y 3x 9?, There is only one zero because it is linear, and can therefore only cross the x axis once.
Frequently Asked Question:
How do you find the inverse of a function?
Finding the Inverse of a Function
- First, replace f(x) with y . …
- Replace every x with a y and replace every y with an x .
- Solve the equation from Step 2 for y . …
- Replace y with f−1(x) f − 1 ( x ) . …
- Verify your work by checking that (f∘f−1)(x)=x ( f ∘ f − 1 ) ( x ) = x and (f−1∘f)(x)=x ( f − 1 ∘ f ) ( x ) = x are both true.
What is the rule of inverse function?
In mathematics, an inverse function (or anti-function) is a function that “reverses” another function: if the function f applied to an input x gives a result of y, then applying its inverse function g to y gives the result x, i.e., g(y) = x if and only if f(x) = y.

What is the formula for inverse?
Notes on Notation
| f-1(x) | f(x)-1 |
| Inverse of the function f | f(x)-1 = 1/f(x) (the Reciprocal) |

Thus, the multiplicative inverse of 8 is 1⁄8.
What is the additive inverse of 8?
Additive inverse refers to any number that when added to the original number gives the result as zero. For instance, the additive inverse of 8 is -8 as 8 + (-8) = 0. It is possible to get the additive inverse of negative numbers too. For example, the additive inverse of -10 will be 10 as -10 + 10 = 0.
What is the inverse of 5?
The multiplicative inverse of 5 is 1/5.
What is the inverse of 6?
The multiplicative inverse of 6 is 1/6.
What is the inverse of +4?
The multiplicative inverse of 4 is 1/4.
How do you find the inverse function rule?
How to Find the Inverse of a Function
- STEP 1: Stick a “y” in for the “f(x)” guy:
- STEP 2: Switch the x and y. ( because every (x, y) has a (y, x) partner! ):
- STEP 3: Solve for y:
- STEP 4: Stick in the inverse notation, continue. 123.
What is the main idea of inverse functions?
An inverse function is a function that undoes the action of the another function. A function g is the inverse of a function f if whenever y=f(x) then x=g(y). In other words, applying f and then g is the same thing as doing nothing.
