Hi, jennifer.
00:02
Thank you for a question.
00:03
So this one, we're given the function, f of x equals absolute value of x over x.
00:10
So first one is f of negative 9.
00:18
This is equal to the absolute value of negative 9 over negative 9.
00:28
So we got 9 over negative 9, which is negative 1.
00:36
Second one, f of negative 6.
00:46
This is equal to absolute value of negative 6, divided by negative 6.
00:54
So it's 6 over negative 6, which is negative 1.
01:00
And the third one is f of 0.
01:05
This one you also got the correct.
01:10
This is undefined.
01:17
Because the denominator cannot be 0, right? the first one is f of 2...
