What is the inverse of the function f(x)=x+3

(x) = x - 3

let y = x + 3 and rearrange making x the subject

x + 3 = y ← ( subtract 3 from both sides )

x = y - 3 ( change y to x )

( x) = x - 3

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8
