 Hi, and welcome to our session. Let us discuss the following questions. The question says, evaluate the following limits and exercises 1 to 22. Limit of x minus 22 by 7 as x tends to 5. Before solving this question, we should know that if fx is a polynomial function, then limit of fx tends to a is equal to f of a. So limit of fx is the value of f at the point x equals to a. The knowledge of this is the key idea in this question. Let's now begin with the solution. In this question, we have to evaluate limit of x minus 22 by 7 as x tends to 5. Now x minus 22 by 7 is a polynomial function, and we have learned in the key idea that if fx is a polynomial function, then limit of fx is x tends to a is f of a. So by the key idea, limit of x minus 22 by 7 as x tends to 5 is 5 minus 22 by 7. Hence, our required limit is 5 minus 22 by 7. This is our required answer. So this is the key to the section 5, and take care.
