Best ResponseYou've already chosen the best response.3xintercepts? this is an equation in one variable.... how do you do that?

Best ResponseYou've already chosen the best response.3ahh.... 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....

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

Best ResponseYou've already chosen the best response.22 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.

Best ResponseYou've already chosen the best response.3hold 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"

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

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

Best ResponseYou've already chosen the best response.1parabolas always have 2 xintercepts unless k=0, is it not?

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

Best ResponseYou've already chosen the best response.3in 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 ????

Best ResponseYou've already chosen the best response.2Perhaps 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...

Best ResponseYou've already chosen the best response.1dpalnc solved it, x=5  sqrt(17/2) x=5+ sqrt(17/2)

Best ResponseYou've already chosen the best response.3compare 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....

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

Best ResponseYou've already chosen the best response.3dang 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.... :)

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

Best ResponseYou've already chosen the best response.0this 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....

Best ResponseYou've already chosen the best response.0this is not a function

dpaInc

Best ResponseYou've already chosen the best response.3right... 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...

Best ResponseYou've already chosen the best response.0no. this is just not a function. nothing more; nothing less

Best ResponseYou've already chosen the best response.1this 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...
