In this question, they say, if you have a parametric equation grapher, graph the equations over the given intervals.
00:07
Here we have x equals 2t plus 3 and y equals t squared minus 1.
00:13
We're on the t interval from negative 2 to positive 2.
00:16
And we use a graphing calculator in order to sketch this curve.
00:21
So let's go to a graphing calculator.
00:23
And the first thing we're going to do is go to mode.
00:26
And you're usually in function mode.
00:29
But we're going to go to parametric mode.
00:32
So scroll down to the fourth or fifth line and click on parametric mode if you're not already there.
00:39
Then go to y equals.
00:41
When you do, you'll see x as a function of t and y as a function of t.
00:48
If you have anything in there, clear those out.
00:52
And then where it asks for x of t, we are putting in 2t plus 3.
00:59
When you click that xt theta n button and you're in parametric mode, a t will appear.
01:07
For y of t, we have t squared minus 1, t squared minus 1...
