Best ResponseYou've already chosen the best response.0I have to plo\[g(t)=u(7t+\sqrt{3})\] and find at what points the function is discontinuous.

Best ResponseYou've already chosen the best response.0Example:\[f(t)=u(3t7)\]\[3t7=0\]\[3t=7\]\[t=\frac{ 3 }{ 7 }\]dw:1440369141852:dw

Best ResponseYou've already chosen the best response.0Another Example: \[h(t)=u(3t+7)\]\[3t+7=0\]\[3t=7\]\[t=7/3\]dw:1440369295368:dw

Best ResponseYou've already chosen the best response.0that is where wherever the shift is taking place is where the discontinuity is

Best ResponseYou've already chosen the best response.0oh that makes more sense, so if I solve for 0, shouldn't I get when t=0?

Best ResponseYou've already chosen the best response.0and from the examples I was given, it seems that at those points is where the shift happens

Best ResponseYou've already chosen the best response.0i think you should really be thinking of what a function is and how transformations work

Best ResponseYou've already chosen the best response.0it just so happens that for this function solving for u(f(t)) where f(t)=0 is the discontinuty as u(0) is discont there

Best ResponseYou've already chosen the best response.0i say this because there might be some other ways to restrict this funtion that is not begin considered right now

Best ResponseYou've already chosen the best response.0So the shift doesn't always occur when it's at 0?

Best ResponseYou've already chosen the best response.0i dont know what you should really be thinking about is the bigger picture though that setting to 0 is more like a formula

Best ResponseYou've already chosen the best response.0or only if we follow dw:1440370174580:dw

Best ResponseYou've already chosen the best response.0you understand how function transformations work right like say g(t) and f(t) = a*g(b(tc)) + d a,b,c,d are constants

Best ResponseYou've already chosen the best response.0f(t) is g(t) with vertical stretch of factor a, horizontal compression of b, shift to right of c and vertical shift of d

Best ResponseYou've already chosen the best response.0yeah thats all u need to know

Best ResponseYou've already chosen the best response.0and the definition of u(t) which u have

Best ResponseYou've already chosen the best response.0for example they can give u something like this, they you wouldnt worry about just setting bracket =0

Best ResponseYou've already chosen the best response.0there will be other places where the function is not defined like this

Best ResponseYou've already chosen the best response.0or suppose they started throwing t into radicals or having abs values in there and stuff like that

Best ResponseYou've already chosen the best response.0I don't think I'm ready for all that yet lol. I've only seen this for 1 class and I still have 1 doubt with the direction of the plot

anonymous

Best ResponseYou've already chosen the best response.0Like for the second example, what made the plot switch directions?dw:1440370886926:dw
