Given this limit and we're asked to evaluate it.
00:02
So this limit, the limit as x approaches negative 4 of 2x squared minus x minus 7.
00:08
And so we can just use limit properties.
00:11
And so that's going to be equal to the limit as x approaches negative 4 of 2x squared minus the limit as x approaches negative 4 of x minus the limit as x approaches negative 4 of negative 4 of negative 7.
00:30
And so this right over here, well, 2x squared is continuous everywhere, so i can just plug it.
00:38
So are this limit over here just going to be equal to the value of the function at that point? value of this function at this point.
00:49
And so this is going to be equal to 2 times negative 4 squared minus.
00:55
Well, the limit as x approaches negative 4 of x is going to be negative 4.
01:00
Minus and since this over here is a constant, this limit over here is just going to be negative 7...
