Misc 2 If f(x) = x2, find (š‘“(1.1) āˆ’ š‘“(1))/((1.1 āˆ’ 1 ) ) Let us first find f(1.1) and f(1) For f(1.1) f(1.1) = (1.1)2 = 1.1 Ɨ 1.1. = 1.21 For f(1) f(1) = 12 = 1 Ɨ 1 = 1 Now, (š‘“(1.1) āˆ’ š‘“(1))/((1.1 āˆ’ 1 ) ) = ((1.1)^2 āˆ’(1)^2)/((1.1 āˆ’ 1) ) = (1.21 āˆ’ 1)/(1.1 āˆ’ 1) = 0.21/0.1 = 2.1
