10-155.

Suppose that *x* = 9*t*^{2} and *t*.

Express

*x*as a function of*y*.Express

*y*as a function of*x*.How would the graph of the parametric equations above be different if

*x*=*u*andfor all real *u*?

Look at the equation for *y*. (3*t*)^{2} = 9*t*^{2}

Solve your equation from part (a) for *x*.
