Question

how do you graph x=e^-t and y=e^3t

Answer 1

its a set of parametric equations

so take the 1st equation and make t the subject.

then substitute into the 2nd equation...

and you'll have something you can plot

Answer 2

i got y=x^-3 but the values i got on the calculator didn't look like the graph that my teacher had posted

Answer 4

x=e^-t and y=e^3t

hmm, are we able to convert the first into the second .....

x = e^-t

x e^(4t) = e^-t e^(4t)

x e^(4t) = e^(3t)

lol, that didnt work out like i wanted it too
