The diagram shows the graph of π¦ equals π of π₯.
00:00:05.313 --> 00:00:09.843
What is the solution set of the equation π of π₯ equals zero?
00:00:10.703 --> 00:00:13.323
We know that π¦ equals π of π₯.
00:00:13.623 --> 00:00:16.793
And weβre looking for the place where π of π₯ equals zero.
00:00:17.113 --> 00:00:21.163
That will be the place for this quadratic where π¦ equals zero.
00:00:21.803 --> 00:00:25.303
And π¦ equals zero at the π₯-intercept.
00:00:26.273 --> 00:00:29.183
π¦ equals zero along the π₯-axis.
00:00:29.463 --> 00:00:34.223
And this function is crossing the π₯-axis at negative two.
00:00:34.773 --> 00:00:38.323
Therefore, the π₯-intercept is negative two, zero.
00:00:38.993 --> 00:00:46.133
But the solution set will be the π₯-value that makes π of π₯ equal to zero.
00:00:46.663 --> 00:00:51.523
And that means instead of coordinate form, weβre only interested in the π₯-coordinate.
00:00:52.063 --> 00:00:56.073
This function equals zero when π₯ equals negative two.
00:00:56.583 --> 00:01:01.573
Therefore, the solution set will only include the value negative two.
