00:00My friends are asking me to plot the graph of the function y = 2 times x - 4.
00:05What were we doing now, guys?
00:06First, let's plot the graph of y equals 2 times x minus 4, without the absolute value.
00:11y equals fx is our function.
00:18We know our missing coordinates, we know our coordinate plane, folks.
00:21So, what were we doing, guys?
00:23We were saying that for x equals 0.
00:26We were finding the point where x equals 0 intersects y.
00:29What can we conclude from this, friends?
00:31If we put x back in at 0, we get minus 4, right?
00:33For y equals 0.
00:36So what happens then, guys?
00:382 times x minus 4 equals 0.
00:40Our x equals 2.
00:42x equals 2.
00:44Now, normally our friends
00:46while cutting our x at 2
00:48Our y is minus 4.
00:55What is this, guys?
00:56The graph of y equals 2 times x minus 4.
01:00So, I consider this to be of absolute value.
01:03When I moved on to the absolute value stage, my friends...
01:07What am I doing?
01:09x is greater than 2,
01:11Let's put it this way,
01:13When x equals 2, the same thing will happen again, friends.
01:16Because the critical point is,
01:17This is the point that resets the content.
01:20Right, guys?
01:20The part that remains above x after this point,
01:27our correct part,
01:28What's up, guys?
01:29because of our ray.
01:29Hattar says:
01:31What's up, guys?
01:32Positive values, right?
01:34This place remains.
01:35Because our focus is positive.
01:37But this minus 4,
01:38this part, friends,
01:40So what do we do again with respect to the x-axis?
01:42We take its symmetry.
01:44Let's do it right away.
01:48Let's say I did it like this.
01:51What happens because this part was taken symmetrically, guys?
01:57This place,
01:57This part is equal to this point.
02:00Isn't it?
02:00If it's minus 4 here,
02:02It should be a 4 here.
02:03Let its symmetry be its reflection.
02:05Our positions are equal from here.
02:06In absolute value,
02:08We say it's the graph of 2 times x minus 4.
