Let f(x) = vi + 28 . We will use the definition of derivative to find the derivative of f (I). () What is the definition of derivative of f (I) ? Of' (z) = lim f(ath) f(z h) h +0 h Of (z) f(ith) f(z) h Of (z) = lim f(3th)-f(z) h Of' (I) = lim f(142 h)-f(zth) h 0 2 h [i) Which one is the correct statement (the next step to find f (x) by definition)? Of(z) = lim vath+ 28 - VI + 28 h Of'(z) = lim VI th + 28 - I -h + 28 h Of'(z) = lim V/I F 28 +h - Vz + 28 h +0 h Of(z) _ VI th + 28 - VI + 28 h [ii) Which one is the correct statement (the next step to find f(x) by definition)?
