In this question, we are asked to calculate the value of the function f at the given points.
00:05
The first point is x equals negative 1.
00:09
And since negative 1 is less than 0, we are in the first case.
00:17
And this means we are going to use 3x plus 3 4f.
00:24
And after plugging in x equals negative 1, we are going to get 3 times negative 1 plus 3.
00:30
That's going to be negative 3 plus 3 and this equals to 0.
00:36
This is the value of the function at negative 1.
00:40
Next, f of 0.
00:44
Well, 0 equals to 0, right? and when x equals to 0, we are in the second case, because that's when x is allowed to be equal to 0.
00:54
And in that case, the formula is 4x plus 6...
