Answer:
![\frac{11}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B11%7D%7B2%7D)
Step-by-step explanation:
To obtain the inverse of f(x)
let y = f(x) and rearrange making x the subject, that is
y = 2x - 1 ( add 1 to both sides )
y + 1 = 2x ( divide both sides by 2 )
= x
Change y back into terms of x with x =
(x) , thus
(x) = ![\frac{x+1}{2}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%2B1%7D%7B2%7D)
Evaluate g(3) and substitute the value obtained into
(x)
g(3) = 3² + 1 = 9 + 1 = 10, then
(10) =
= ![\frac{11}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B11%7D%7B2%7D)
Theres about a 7,200,000 difference between household dogs vs household cats
> First let us compute for the total sales the three
people made.
Total sales = $2030 + $1540 + $1800 = $5370
Therefore the fractional sales are:
Lola = $2030/$5370 = 203/537 = 0.378
Ahmed = $1540/$5370 = 154/537 = 0.287
Tommy = $1800/$5370 = 180/537 = 0.335
> The bonus they each received is:
Lola = 0.378 ($100) = $37.8
Ahmed = 0.287 ($100) = $28.7
Tommy = 0.335 ($100) = $33.5
