Graph of function is given and we need some straightforward values which are straight at f of minus 3.
00:07
F of minus 3 means the functional value at x equal to minus 3.
00:10
Where is minus 3? this is 0.
00:12
So this is negative 1, negative 2, negative 3.
00:15
And in negative 3, the functional value is this which is 1 and this is 2.
00:20
So this is 2 from the graph.
00:23
Likewise, f of 2.
00:24
Where is 2 is 2 is or this is 1, this is 2 and a 2 if we go, that is somewhat less than this particular value.
00:34
So this is one, this is two, this is three.
00:36
I think this is a little less than three.
00:38
I mean, if you want to approximate, we can do it as 2 .9.
00:42
For what value is x is fx negative one? fx is negative one means the value of y is negative one.
00:50
Where is negative one? this is zero and this is negative one.
00:53
So the function is negative one.
00:55
If we draw a straight line on negative one, then where is the function negative one? at this value of x at this value of x and at this value of x at this particular point what is x that's zero right because that is lying on the y axis and in y axis x is zero so one of the value of x is zero and another value is another value is negative which is uh negative one and negative two so this value is coming as negative two so this is negative two over here likewise, estimate the values of x when fx is 0.
01:31
So once again, where is fx0? fx is zero means if they are talking about the x intercepts.
01:37
So x intercepts mean the x axis...
