Best ResponseYou've already chosen the best response.0state the direction and the # of in which the graph of each function is translatedfrom the graph of f(x) = x squared

Best ResponseYou've already chosen the best response.0this is a graph...sorta of what you got

Best ResponseYou've already chosen the best response.0x^2 normally rests on the xaxis, but this one is moved up by 8 units

Best ResponseYou've already chosen the best response.0If we let g(x) = \(x^2\) and f(x) = \(x^2+8\). We can see that f(x) will always be 8 units higher on the y axis than g(x) is. Thus f(x) is a translation of the graph of \(x^2\) up 8 units.

Best ResponseYou've already chosen the best response.0it is neither wider nor narrower than x^2, since there is no number other than a 1 infront of the x^2 part.

Best ResponseYou've already chosen the best response.0larger than one tends to make the slope steeper... and narrows the graph a fraction of a slope tends to flatten the slope and widen the graph

Best ResponseYou've already chosen the best response.0what if there is no y intercept like f(x) = 2x squared

amistre64

Best ResponseYou've already chosen the best response.0the y intercept is there...its just zero :)

Best ResponseYou've already chosen the best response.0y intercept just means tha the line of the graph gets intercepted, cuahgt by, crosses over, the y axis at a certain point. another name for the y axis is x=0. so whenever x=o you can find the y intercept

Best ResponseYou've already chosen the best response.0y = 2(0)^2...the y int = 0

Best ResponseYou've already chosen the best response.0y = (0)^2 + 8 the y int = 8

Best ResponseYou've already chosen the best response.0so if x=o there is no direction?

Best ResponseYou've already chosen the best response.0you have to define what you mean by "direction"

Best ResponseYou've already chosen the best response.0like on the first problem u found out the the graph is going 8 units

Best ResponseYou've already chosen the best response.0y = (x + "moves it side to side")^2 + "moves it up or down"

Best ResponseYou've already chosen the best response.0you understand that little "equation" I made?

anonymous

Best ResponseYou've already chosen the best response.0i think so like if it were to be f(x)=2x sqaured the y will be a zero? so that will mean it has no direction?

amistre64

Best ResponseYou've already chosen the best response.0correct as far as I am understaning your choice for "direction".. it simply means that the graph itself hasnt moved anywhere....but that "2" there means that the graph did get steeper...narrower

Best ResponseYou've already chosen the best response.0ok one more question how would u graph all of this usin y=mx+b or no

amistre64

Best ResponseYou've already chosen the best response.0id go with no,.... y = mx +b makes a line...not a curve y = Mx^2 + b makes a curve since it has a "2" on the x. starts to bend the line
