Question

What is the inverse of f(x) = 3x + 6 and is it a function?

X-2, Yes
X-6/3, yes
X-1/2 , No
X - 1 , No

Answer 1

Explanation:

F(x)=3x+6

let y=f(x)

y=3x+6

to find the inverse of a function easily.

you just need to switch the variables

then make y the subject of formula

x⇒y and y⇒x

y=3x+6

x=3y+6

3y=x-6

y=x-6/3

the inverse of the function

f(x)=3x+6

f(x) ⁻¹= x-6/3

Answer 2

f-1 (x) = x/3 -2

this is the one
