Students we are given a question that write a real life based problem and solve it by graph.
00:04
Okay, so we can we can suppose that let there is a boy let let say frank okay let frank earns $5 in an hour or we can say it as per hour five dollar per hour and a bonus of two dollar as well.
00:37
Okay now we are asked that how much frank earns in two hours okay students it is our question let's say now what we can suppose let time be t okay and earning be e of t okay so what we can say that e of t can be written as see the per hour earning can be written as 5 t and what is bonus the additional bonus is nothing but two so the total earning can be written in the form of t function which can be written as 5t plus two okay now we can write it as let's say what we are asked how much it earn in the two hours it means we just need to check for t is equals to two and hours okay now we will solve it by the method of graph okay so how we will solve it see let's say this is our graph okay students now what we are asked to see we can put here 1, 2, 3, here 4, after that 5, okay? let's say it is in the t.
01:56
Now, it is, let's say, 0.
01:57
And we are supposed to know that the t cannot be negative.
02:01
So we just don't need to write the negative terms also, and the earning also cannot be negative.
02:05
See, we will see the only first for it.
02:07
Let's say here, it is 2, 4, 6, 8.
02:13
After that we can even make it a little bit larger okay so what we can do here it is 10 12 and okay up to 12 let's say it is in the et format it is in the it is it is the xx is okay now what we are supposed to do is equal to 5t plus 2 it means when we put a t is equal to 0 what we'll get it is et is nothing but equal to 2 okay so e 0 is nothing what equal to 2 it means the first point can be written as 0 comma 2 okay students and second point let's say t equal to 1 so t equal to 1 at t equal to 1 what we will get 5 plus 2 comes out as 7 it means at 1 it is nothing but 7 okay so basically it is just like that 1 comma 7 okay students so basically we will just meet them okay and it will be like that okay students now after that what we are asked to add to t equal to 2 so basically t equal to 2 it is nothing but equal to the 12...
