every time i try graphing it my calculator says you cannot graph an ineqaulity?

ipwnbunnies · Answer

You don't need a graphing calculator.
Eliminate the parameter. It should be smooth sailing from there.

anonymous · Answer

how do you do that :o

ipwnbunnies · Answer

x = 2t  -->  t = x/2

Plug in x/2 for t  in the second part of the parametric equation.

Oh no, I forgot to talk about the parameters.
The given interval is -2 ≤ t ≤ 3 
But, since we're using 'x' as the independent variable, we need to find the interval of x.

x = 2t ->  When t = -2, x = -4
When t = 3, x = 6
So, the interval you should be graphing on is: -4 ≤ x ≤ 6
