Best ResponseYou've already chosen the best response.0@Nnesha Did I graph these 3 points, right?

Best ResponseYou've already chosen the best response.1hmm \[\huge\rm y=a(xh)^2+k\] vertex form of parabola where (h,k) is the vertex point and find x and y intercepts

Best ResponseYou've already chosen the best response.1xintercept is a point where line intersect xaxis when y=0 so substitute y for 0 to find x intercept yintercept is a point where line intersect yaxis when x=0 so substitute x for y to find yintercept

Best ResponseYou've already chosen the best response.0what are the next steps?

Best ResponseYou've already chosen the best response.1alright and bec a is negative in the question so we would get max point (graph opens down)

Nnesha

Best ResponseYou've already chosen the best response.1so max would be at ((4,1) dw:1443814926678:dw

Best ResponseYou've already chosen the best response.1hmm highest degree is 2 so you should get 2 xintercepts 4 isn't correct

Best ResponseYou've already chosen the best response.1hmm how did you get that ?

Best ResponseYou've already chosen the best response.0I graphed it on my calculator

Nnesha

Best ResponseYou've already chosen the best response.1hmm make sure you typed the correct equation

Best ResponseYou've already chosen the best response.0Alright, I got x=0 and y=63

Best ResponseYou've already chosen the best response.1yeah that's yintercept now substitute y for 0 to find xintercept

Best ResponseYou've already chosen the best response.1\[\huge\rm 0=4(x4)^2+1\] do you know the quadratic formula ?

Nnesha

Best ResponseYou've already chosen the best response.1(x4)^2 is same as (x4)(x4) foil it

Nnesha

Best ResponseYou've already chosen the best response.1familiar with the foil method ?

Best ResponseYou've already chosen the best response.1hmmm better use calculator instead google i didn't get 16

Best ResponseYou've already chosen the best response.1make sure you are looking at the right question

Best ResponseYou've already chosen the best response.1i have no idea how u got that please show some work we need x intercepts when y =0

Best ResponseYou've already chosen the best response.0sighs I typed it in my calculator. (x4)^2 and graphed, it showed x=0 and y=16

Nnesha

Best ResponseYou've already chosen the best response.1hmm well ur equations is 4(x4)^2 +1 that's what u should type into the calculator

Nnesha

Best ResponseYou've already chosen the best response.1will if you want to solve by hand to find xitnercepts then yes there are lots of steps if you want to use calculator then there are none

shaleiah

Best ResponseYou've already chosen the best response.0Alright, I typed it in. Graphed. X=0

Best ResponseYou've already chosen the best response.1or here is another way to graph xcoordinate of vertex is 4 right so draw a table dw:1443819080897:dw now substitute those points to find y coordinate

Nnesha

Best ResponseYou've already chosen the best response.1no i have so man tabs open so that's why

Nnesha

Best ResponseYou've already chosen the best response.1do you understand that ?

Nnesha
 one year ago
Best ResponseYou've already chosen the best response.1don't need to find xintercepts just substitute x for the points in the table that's it

Best ResponseYou've already chosen the best response.1vertex is max point min = minimum max = maximum dw:1443820566646:dw

Best ResponseYou've already chosen the best response.1dw:1443820718145:dw if the vertex is at (4,1) that would be the maxx point

Nnesha

Best ResponseYou've already chosen the best response.1dw:1443820739973:dw this point should be the max that's why to find other two points we should go up 2 and down 4 from the xcoordinate of the vertex

Best ResponseYou've already chosen the best response.1dw:1443820778704:dw use this table substitute x for its value from the table then solve for y
