The image shows a geometric representation of the
function f(x) = x2 - 2x - 6 written in standard form.
What is this function written in vertex form
f(x) = (x-1)²-7
f(x) = (x + 1)2 - 7
f(x) = (x - 1)2 - 5
f(x) = (x + 1)2 - 5

Correct option is A)   .

Step-by-step explanation:

Here we have , The image shows a geometric representation of the  function f(x) = x^2 - 2 x - 6 written in standard form.We need to find What is this function written in vertex form . Let's find out:

Basically we have a function  , and we need to convert it into perfect square as:

⇒  

Adding & subtracting 1 ,

⇒  

⇒               {  }

⇒  

⇒  

Therefore , Correct option is A)   .

the best buy, is the 4- kilogram bag of lollipops for $18.40.

step-by-step explanation:

i found my answer by dividing the cost of each bag by their respective weights.

14.88 divided by 2 = 7.44

17.29 divided by 3 = 5.77

18.4 divided by 4 = 4.6

24.4 divided by 5 = 4.88

by this, i found that the 4 kilo bag is the best buy.
