So in this question, basically you ask you to applaud the function, right? this function is really, it's really shooting this diagram, right? and the second -old piecewise polynomial, right? so, i mean, you look at this specific to why, right, this function as a function of x, it's polynomial.
00:21
So it's likely to be second -word piecewise as a word.
00:25
So it's basically, if you look at each part of it, for example, look at this part, it's kind of part of parts of the parabolic, right? this is kind of part of the parabolic.
00:40
So it's very clear that actually so obviously this function can be reading this form, right? it's the first for x from 4 to 0, right? and this function is basically a palatbolic because it's a second order polynomial so basically it's a palatolic, right? and see that it's actually a symmetric about this part, right? this section is symmetric about the wax system.
01:06
So you know that it must be of the simple form, a x squared plus b, right? and for the other part, x is like then to eight, right? and for this part, it's also palabolic, but now you see the center is actually shift to eight, right? and so it's going to be given by basically a x minus eight squared, right? it's going to be like this and plus b, of course.
01:31
And you can actually, so this is a function right, and you can actually find a and a b, right? so from the values you are giving here, for example, b, if you said x equals zero, b obviously is given by about something at five, right? so we get b equals five...
