Okay, so in a, i want the domain of this function.
00:07
Your domain is all real numbers.
00:13
In interval notation, that is negative infinity to positive infinity.
00:20
The range of this function, though, is not all real numbers.
00:24
The range is your y values, and you can see that you are at negative 4 on that y -axis, and the graph is entirely below that.
00:34
So it's y is less than or equal to negative four.
00:39
Again, as an interval, that's negative infinity, negative four with a bracket.
00:50
X intercepts, there are none...
