xintercepts? this is an equation in one variable.... how do you do that?

Am I suppose to distribute the 2?

dpaIncBest ResponseYou've already chosen the best response.3
ahh.... my bad.... because this is an equation in one variable, it is just a vertical line.... so solving for x will give you the only xintercept....

panlac01Best ResponseYou've already chosen the best response.1
since this is a quadratic function, you will get 2 values for the xintercepts. read pp 126129 in the link I've posted above.

2 xintercepts? \[2(x5)^2=17\]Divide both sides by 2\[(x5)^2=\frac{17}{2}\]Take square roots for both sides \[(x5)=\pm \frac{17}{2}\]Add 5 to both sides to get the answer.

oh okay thank you that makes so much sense :)

dpaIncBest ResponseYou've already chosen the best response.3
hold on folks... this is an equation in x only.... this is a vertical line.... and not a function.... "Find the xintercepts: 2(x5)^2=17"

RolyPolyBest ResponseYou've already chosen the best response.2
Wow. That's complicated. I thought all I had to do was to solve it but seems not :(

dpaIncBest ResponseYou've already chosen the best response.3
this is a function: y = 2(x5)^2 this is not a function: 17 = 2(x5)^2

parabolas always have 2 xintercepts unless k=0, is it not?
 one year ago

RolyPolyBest ResponseYou've already chosen the best response.2
But how to get the xintercept(s)??? There is no y...
 one year ago

dpaIncBest ResponseYou've already chosen the best response.3
in any function, to find the xintercepts, set y=0 and solve.... how are you gonna set y=0 in the equation 2(x5)^2 =17 ????

Think the xintercept is 8.5,0

RolyPolyBest ResponseYou've already chosen the best response.2
Perhaps this would be the case? y = 2(x5)^217 Put y=0 2(x5)^217 = 0 2(x5)^2=17 . . . Solve x to find the xintercepts. Hmm...

dpalnc solved it, x=5  sqrt(17/2) x=5+ sqrt(17/2)

dpaIncBest ResponseYou've already chosen the best response.3
compare these two equations: y = x + 3 and 17 = x + 3 that first one is a line and you can find the xintercept by setting y=0 then solving 0 = x + 3. but that second equation is just a vertical line....
 one year ago

RolyPolyBest ResponseYou've already chosen the best response.2
Eh?! Then, for 17=x+3, the xintercept is 173 = 14?!

dpaIncBest ResponseYou've already chosen the best response.3
dang this chrome browser.... x = 14 is a vertical line and that's where it crosses the xaxis.... but back to the problem... did i say 1 xintercept? i mean two as panlac says.... :)

a vertical line that curves...obviously troll ^^

dpaIncBest ResponseYou've already chosen the best response.3
how 'bout two vertical lines... it's implied when u solve a quadratic you have to consider the positive and negative square root....

lgbasalloteBest ResponseYou've already chosen the best response.0
this goes against the teachings of the monks... the forefathers defined xintercept as "the value of y when x is 0" however, there is no y....

lgbasalloteBest ResponseYou've already chosen the best response.0
this is not a function
 one year ago

dpaIncBest ResponseYou've already chosen the best response.3
right... so when you solve for x in that equation, you get two vertical lines... an equation in only 1 variable x is not a function...

no. this is just not a function. nothing more; nothing less

you were saying it had an xintercept

it has values for x...but no xintercept

so are you saying that a circle (which is a curve) does not have xintercepts?

yes it doesnt. it's not a function

dpaIncBest ResponseYou've already chosen the best response.3
so why can't you call the where a vertical line crosses the the xaxis the xintercept?

any closed figure is not a function. it is a plane

this is going beyond the problem now... bottom line: x has two values

i would like to quote myself "you got trolled" relations have xintercepts too http://en.wikibooks.org/wiki/Algebra/Intercepts

yes.... let's graph it....

panlac01Best ResponseYou've already chosen the best response.1
this is really going beyond now... why can't we agree that the intercepts are where either the vertical line or horizontal line are touched or crossed? did I start the fire when I said it was a function? I retracted it so OS can be a better place for students once again...
