Thank you We sneak in and here's your smoke too

00:05

Sure brought to you by vertical intercepts It's the natural

00:09

order of things Axes split wood and intercept split axes

00:15

Don't like that Find the vertical intercepted the function F

00:18

ax equals reacts wherein minus seven x plus thirteen And

00:21

here the financial answers pretty All right so what's this

00:27

question asking Well we're looking for a vertical intercept vertical

00:31

So good place to start Might be what is a

00:35

vertical intercept against All right Well here's a typical graph

00:38

and this brat chair is the vertical axis A vertical

00:43

intercept is one that intercepts the vertical access like prostitutes

00:49

Oh english language Sometimes you make sense All right now

00:52

every point along the vertical axis has an x value

00:55

of zero So zero negative five is here Zero zero

00:58

The origin by darling is here and zero four is

01:02

here and so on So if we want to find

01:05

a vertical intercepts we can always just plug in x

01:08

as zero We take the equation given to us f

01:12

of x equals three x squared minus seven plus thirteen

01:17

roll in a few zeros to get f zero equals

01:21

three ton zero squared minus seven times zero plus thirteen

01:26

well in california zero squared zero times three still zero

01:30

and seven times zero is also zero So really we've

01:33

got f zero equals zero minus zero plus thirteen which

01:37

when all is said and done is simply thirteen and

01:40

we've got a vertical intercept Answer D to the rest

01:43

of the answer Choices on those axes We say him 00:01:47.274 --> [endTime] by far
