For this problem, we're looking at taking the greatest integer function, which you see i've plotted, and we're going to shift it up or down in part a based on the value of c.
00:13
So if c is negative 2, then we're adding negative 2 to the function, so we're going to shift the whole graph down 2.
00:32
If c is 0, then we're just adding 0 to the function, so we're not changing the function, so we just have the function in its original position.
00:49
And if c is positive 2, then we're going to shift the whole graph up to.
01:06
And for part b, we're starting with the same function, y equals the greatest integer of x.
01:12
And what we want to do is add or subtract c inside the function instead of outside the function.
01:17
And so that's going to shift it left or right.
01:19
So if c is negative 2, then we have x minus 2.
01:23
That shifts it to the right 2.
01:38
If c is 0, it doesn't shift it at all...
