y -intercept where line cross y-axiss and x-intercept where line cross x-axis did you graph it on a calculator ?
anonymous
  • anonymous
no
Nnesha
  • Nnesha
if the highest degree is a odd number and the leading coefficient is negative then right end will fall and left end will rise **and if the leading coefficient is positive then right side will rise and left will fall

alright graph that equation first
Nnesha
  • Nnesha
btw you DON'T have to for y-intercept (when line touch the y -axis x=0) so plug in 0 for x solve for y x-intercept when y =0 so plug in 0 for y solve for x

Root plot for : y = x2-7x+12 Axis of Symmetry (dashed) {x}={ 3.50} Vertex at {x,y} = { 3.50,-0.25} x -Intercepts (Roots) : Root 1 at {x,y} = { 3.00, 0.00} Root 2 at {x,y} = { 4.00, 0.00}

hmm
Nnesha
  • Nnesha
nah i can easily figure out that graph is wrong bec highest degree is odd which is 3 your graph should be like this |dw:1437394937194:dw|
Nnesha
  • Nnesha
this is parabola http://assets.openstudy.com/updates/attachments/55ace58fe4b0ce10565a87f0-hamza123-1437394782395-canvas.png

so what is the x-intercept
Nnesha
  • Nnesha
https://www.desmos.com/ use this calculator or replace y by 0 solve for x

what is the end behavior
Nnesha
  • Nnesha
\(\color{blue}{\text{Originally Posted by}}\) @Nnesha if the highest degree is a odd number and the leading coefficient is negative then right end will fall and left end will rise **and if the leading coefficient is positive then right side will rise and left will fall \(\color{blue}{\text{End of Quote}}\) ^
Nnesha
  • Nnesha
\[\huge\rm Ax^3+Bx^2+Cx+D\] A is leading coefficient 3 is highest degree
anonymous
  • anonymous
so 3
Nnesha
  • Nnesha
what about 3 ?
anonymous
  • anonymous
the end behavior
Nnesha
  • Nnesha
\(\color{blue}{\text{Originally Posted by}}\) @hamza123 Root plot for : y = x2-7x+12 Axis of Symmetry (dashed) {x}={ 3.50} Vertex at {x,y} = { 3.50,-0.25} x -Intercepts (Roots) : Root 1 at {x,y} = { 3.00, 0.00} Root 2 at {x,y} = { 4.00, 0.00} \(\color{blue}{\text{End of Quote}}\) you graphed the wrong equation :/........
Nnesha
  • Nnesha
nope highest degree is 3 what about leading is it negative or positive ?
Nnesha
  • Nnesha
leading coefficient *
anonymous
  • anonymous
postive
Nnesha
  • Nnesha
yes so right side will rise and left side will fall
Nnesha
  • Nnesha
this is the graph http://prntscr.com/7uthm4 of x^3 +15x^2 +68x-96
anonymous
  • anonymous
(3,0) x -int
Nnesha
  • Nnesha
yep one x-intercept is 3 there are more..
Nnesha
  • Nnesha
how many times graph is crossing the x-axis or highest degree represent the number of x-intercept
Nnesha
  • Nnesha
highest degree is 3 so = 3 x-intercept
anonymous
  • anonymous
so what about y-int
Nnesha
  • Nnesha
desmos.com graph the equation zoom out a little bit you will see the point where line cross y-axis that is your y-intercept
Nnesha
  • Nnesha
or \[\huge\rm y =x^3 +15x^2 +68x-96\] or replace x by 0 solve for y
anonymous
  • anonymous
y-int (1,8)
Nnesha
  • Nnesha
nope when line cross y-axis x equal to 0 so x is 0
anonymous
  • anonymous
i cant find it
Nnesha
  • Nnesha
replace x by 0 let me know what you get
anonymous
  • anonymous
(0,8 )
Nnesha
  • Nnesha
how did you get 8 ?
Nnesha
  • Nnesha
show your work plz
anonymous
  • anonymous
i keep on looking at desoms graph
anonymous
  • anonymous
can tell me what it is
Nnesha
  • Nnesha
did you graph it on desmos ??
anonymous
  • anonymous
yes
Nnesha
  • Nnesha
okay hit the zoom out button you will see the point
anonymous
  • anonymous
0,-96
Nnesha
  • Nnesha
yes
anonymous
  • anonymous
ii just need the end behavior
Nnesha
  • Nnesha
read the my comments again you will find out
anonymous
  • anonymous
3
Nnesha
  • Nnesha
nope end behavior meaning define the graph when it's increasing or decreasing it's not gonna be a number
anonymous
  • anonymous
increasing because the leading coefficient is positive
Nnesha
  • Nnesha
both ends are increasing ?
Nnesha
  • Nnesha
\(\color{blue}{\text{Originally Posted by}}\) @Nnesha if the highest degree is a odd number and the leading coefficient is negative then right end will fall and left end will rise **and if the leading coefficient is positive then right side will rise and left will fall \(\color{blue}{\text{End of Quote}}\) read this please leading coefficient is positive so how right end behave and how left side behave
anonymous
  • anonymous
yup your right
