(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Find a parameterization for the motion described by x = -3z^2 in the xz plane.

2. Relevant equations

3. The attempt at a solution

For circles and stuff, I get the general process, but for these simple ones, they feel a little too easy.

Is it valid for me to say:

let x(t) = t

then z(t) = -3t^2

and y(t) = 0 because of it's location in the plane constantly of xz.

Can I always just solve the equations for one side and define it to be equal to t, adjusting the remaining equation(s) accordingly?
