Question

Please quickly help!! I will Mark brainliest, What is the inverse of the function f(x) = x +3? Thank you!

Answer 1

Answer:

Mark me as Brainliest

$fx^{-1} (x)=x+3$

Step-by-step explanation:

To find the inverse of a function, just “trade” x and y and solve for the “new” y. The graph of the inverse is the reflection of the original function over the line y=x.

Rewrite the function

$f(x)=x+3$

as the equation, y=x+3

Trade x and y.

X=y+3

The symbol for the inverse if $fx^{-1} (x)$

$fx^{-1} (x)=x+3$

Answer 2

Answer:

x-3

Step-by-step explanation:

hlo therre!!

f(x)=x+3

let f(x) be y;

y=x+3

now; interchanging the value of x and y;

i.e. x=y+3

y=x-3

f(x)^-1 = x - 3...

this is the required inverse function..

thank u!! hope it helps!
