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

Am I suppose to distribute the 2?

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....

panlac01 Group TitleBest 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 :)

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"

Wow. That's complicated. I thought all I had to do was to solve it but seems not :(

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?

RolyPoly Group TitleBest ResponseYou've already chosen the best response.2
But how to get the xintercept(s)??? There is no y...
 2 years ago

dpaInc Group TitleBest 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

RolyPoly Group TitleBest 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)

dpaInc Group TitleBest 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....
 2 years ago

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

dpaInc Group TitleBest 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 ^^

how 'bout two vertical lines... it's implied when u solve a quadratic you have to consider the positive and negative square root....

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....

this is not a function
 2 years ago

dpaInc Group TitleBest 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

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...
