All right, so you asked for the secant of 3x and you wanted on the tia -84.
00:08
Now, unfortunately, i'm on a computer and i can't do that, but i pulled up my favorite calculator, the desnos.
00:14
And i can type in secant of x.
00:18
Now, we actually want a 3x, and so i can go ahead and put that in.
00:23
So state the range of this function.
00:26
As we can see, it goes, comes down and then goes back up.
00:31
I zoom out, it's going to keep going.
00:36
So the range on this would be from negative infinity up until negative one.
00:45
This is negative one.
00:47
And from one to infinity.
00:51
So if i bring some stuff over here, so we got the range is from negative infinity up to one.
01:03
One.
01:03
And one, and it's going to hit negative 1.
01:08
See how we got negative 1 right there...
