Alright, so this problem starts out with a function f of x equals 4x squared.
00:09
So to me, this is a parabola, a quadratic function, right? a parabola that is stretched with a by a factor of 4.
00:16
And they only care about the restriction on the domain from negative 2 to negative 1.
00:24
So they say the domain of f is this interval, negative 2 to negative 1.
00:29
Then your question says the range of f is the interval 1, 4.
00:34
And i wonder if that's right, because when you plug in negative 2, negative 2 squared is 4, and 4 times 4 is 16.
00:43
So i'm wondering if that's supposed to say 16, 4.
00:46
Because when you plug in negative 1, right, negative 1 squared is positive 1, and 1 times 4 is 4.
00:54
So this one works out okay.
00:57
So i'm not sure, okay, how that, what that reads.
01:00
And i can't see the graph.
01:01
It says the graph of f is shown in part a, and i don't have a graph.
01:05
Then it says the graph of g obtained by shifting the graph of f up 4 units...
