Transcript

Misc 2 If f(x) = x2, find (𝑓(1.1) βˆ’ 𝑓(1))/((1.1 βˆ’ 1 ) ) Let us first find f(1.1) and f(1) For f(1.1) f(1.1) = (1.1)2 = 1.1 Γ— 1.1. = 1.21 For f(1) f(1) = 12 = 1 Γ— 1 = 1 Now, (𝑓(1.1) βˆ’ 𝑓(1))/((1.1 βˆ’ 1 ) ) = ((1.1)^2 βˆ’(1)^2)/((1.1 βˆ’ 1) ) = (1.21 βˆ’ 1)/(1.1 βˆ’ 1) = 0.21/0.1 = 2.1
