 Hi and welcome to the session. Let us discuss the following question which says, if fx is equal to x square, find the value of f 1.1 minus f at 1 upon 1.1 minus 1. So, let us start with the solution and the given function is fx is equal to x square and we are required to find the value of f 1.1 minus f at 1 upon 1.1 minus 1. So, for that first let us find out the value of the function when x is 1.1. Now, say fx is equal to x square therefore when x is replaced by 1.1 we have 1.1 whole square which is equal to 1.21 and the value of the function at x is equal to 1 and 1 square is further equal to 1. Now, let us find the value of f at 1.1 minus f at 1 upon 1.1 minus 1. Now, when x is replaced by 1.1 the value of the function is 1.21, when x is replaced by 1 the value of the function is 1 and in the denominator we have 1.1 minus 1 which is further equal to 0.21 upon 0.1 which on further simplifying comes equal to 2.1 and thus the required value of the function is 2.1. So, this completes the solution, hope you enjoyed it, take care and have a good day.
