Let f(z) = - 2 . We will use the definition of derivative to find the deivative of f (I) (@) What is the definition of derivative of f (I)? Of' (z) = lim f(342 h)-f(zth) h +0 2 h Of (z) _ f(Eth) f(z) h Of'(z) = lim f(Ith) f(z h) h +0 h Of' (z) = lim f(3th)-f(z) h +0 h (ji) Which one is the correct statement (the next step to find f (z) by definition)? 10 Ofl(z) = lim (zth)2-12 h 10 10 Of ( I ) (Ith)2 10 10 O (Eth)2 2 f' (z) = lim 10 10 Ofl(z) = lim (+ 2h) 2 2 h (mii) Which one is the correct statement (the next step to find f(x) by definition)? 10((z + h)2 -12) Of'(z) = lim h +0 ha2 (x + h)2 Of' (z) = lim 10 h woh( (ith)2 -2) of(z) = lim 10 hwhith-z)2 Of'(z) = lim 10(12 - (z + h)2) h w h2(xth)2 (iv) Which one is the correct statement (the next step to find f)(x) by definition)?
