Sketch the graph of x=t^2 y=1/t for t>0

OpenStudy (anonymous):

Is it like this?|dw:1332336280965:dw|?

OpenStudy (anonymous):

t is? A constant or variable?

OpenStudy (anonymous):

t >0 And value greater than 0

OpenStudy (anonymous):

any value greater than 0, sorry.

|dw:1332183657909:dw| It will be a parabola.

For the precise grap http://www.wolframalpha.com/input/?i=x+%3D+t%5E2

*graph

OpenStudy (anonymous):

True, but won't values for the graph be: t 1 2 3 4 x 1 4 9 16 y 1 1/2 1/3 1/4.......?

OpenStudy (anonymous):

You want a graph between x and y?

OpenStudy (anonymous):

Yes

OpenStudy (anonymous):

x= t^2 y= 1/t t>0

OpenStudy (anonymous):

Then you would have to eliminate t. x = t^2 y = 1/t ---- Squaring this => y^2 = 1/t^2 or t^2 = 1/y^2 Therefore x = 1/y^2
