Let f (x) = 5 x2 + 8 x + 7 . We will use the definition of derivative to find the deivative of f (I) () What is the definition of derivative of f (x)? Of(z) = f(Eth) f(I) Of (z) = lim f(eth) f(x h) h +0 h Of (z) = lim f(z42 h) f(zth) h +0 2 h Of (z) = lim f(Ith)-f(I) h +0 h (ii) Which one is the correct statement (the next step to find f/(x) by definition)?
