Hello student, this is the table for x and f of x, we have to find the value of k.
00:07
First question is, if f is, right, if f is linear.
00:14
If f is linear, we need to find the value of k, right? then linear can be defined like this, f of x is equal to a x plus b.
00:27
Right, now, now for x is equal to 0.
00:31
So what f of x is equal to 4? then 4 is equal to a is multiplied by 0 plus b.
00:42
Then b is equal to 4.
00:44
And another value is for x is 1, f of x value is k.
00:51
Right, then k is equal to write a plus b.
00:57
Right, this is the one equation and another one for x is equal to 2 we will get f of x is equal to 11 then 11 is equal to 2a plus b right already we got b is equal to 4 what we will get 11 is equal to 2 times a plus 4 right now 11 minus 4 is equal to a sorry to a now 7 is equal to 2a then 7 is equal to 2 a then then a is equal to 7 divided by 2.
01:41
Now we got a value and b value.
01:44
Next we need to find the value of k.
01:46
Right...
