Hello.
00:01
So here we're asked, are the given functions linear? so the first function here is going to be c of t, which is going to be equal to 60 minus 2 over t.
00:14
So this is the same thing as, well, 60 minus, well, 2 times t to the negative 1.
00:23
So a linear function is going to be, well, in the form, why, is equal to, you know, ax plus b.
00:30
So we have to have our variable to the first power.
00:35
Well, this is basically t to the negative first power.
00:37
So therefore, this is false, right? this is not linear because the variable t here is really to the negative first power, not to the first power.
00:47
And then the second function is going to be c of n, which is going to be equal to 1 .6n...
