Graph this function, plot 5 points on the graph of the function.
00:09
The first point using the x value that's satisfying the equation, the cubic root of x minus 5 equals 0, and then plot 2 points to the left and 2 points to the right of the first point.
00:25
So let's first solve this first point.
00:28
So cubic root of x minus 5 is 0.
00:31
So we have x minus 5 is 0.
00:35
So x equals 5.
00:36
So the first point we have is 5 .0.
00:41
5 .0 is somewhere about here.
00:50
Then let's find the two points to the right of the first point.
00:55
Let's say 1 x equals 6.
00:58
The cubic root of x minus 5 is cubic root of 6 minus 5, which is 1.
01:06
So the second point is 1 .0.
01:12
When x equals 9, okay, the cubic root of x minus 5 is a cubic root of 4, which is, oh, sorry, here i think i want to make this result a positive, an integer.
01:31
So i choose 13, okay? so cubic root of 13 minus 5 is 8, which is 2.
01:39
Okay.
01:43
So the third point is two, sorry, 13, 2.
01:51
I'm sorry, here the second point is 6 .1, okay? so i have 6 .1 and 13 .2...
