Question

Eliminate the parameter to find a Cartesian equation of the curve. x=t-1, y=t^(3)+1 -2<=t<=2

Answer 1

t = x+1 so,

y = (x+1)^3 + 1

Answer 2

oh thanks I thought we had to find the equation from the y=t^3+1 and get t^3=y-1

Answer 3

do i have to find new coordinates instead of using -2 and 2 do we find new numbers?

Answer 4

yes you should redefine the domain

-2 <t< 2 becomes -3< x< 1 since x = t-1

Answer 5

thank you!!!
