if we have function like this y = ( x - 2 ) ^ 2 + 1, what we will get if we do : y = - ( ( x - 2) ^ 2 + 1 ) , and more to find the top of function ( highest value ) doesnt matter the ( x - 2) ^ 2 ..... for x-2

beacause theres allways is 0 to find the top of function

 

First just to clarify, do you mean these functions?

 

[math]y = (x - 2)^2 + 1[/math]

 

and

 

[math]y = -((x - 2)^2 + 1)[/math]

 

Second, I don't know what you're trying to determine. Can you elaborate?

So far, nobody understood any of your posts.

and this part x ^ 2 also doeasnt matter, bacause the x ^ 2 after set the x = 0 will be 0, so in this function only matter + 1, to find the top of function. and b value must be > 0 , or < 0, its clear

i am trying to find the maximum and minimum of this function. and what else use this equal y = b / x has sense ?

and in equal y = (x-3)^2 + 2, line provide by minimum of this function is y = 3 / 2 x . with equal (x-6)^2 + 1 the line provide by minimum of this function is y = 1/6 x

and what more (b) cant be more ( for x^2 + b ) next values

for example :

y = x^2 + b, x = 1, x = 2, maximum is only 1 point

and the

b < x^2 + b

Edited June 4, 201411 yr by md2

y = (x - 2)^2 / b , for maximum of function y = (x - 2 )^2 + b , for maximum y = 0 , when x = 2

 

 

y

y = ( x - 3 ) ^ 2 + b

b < ( x - 3 ) ^ 2

b = ( x - 3 ) ^ 2 + b
