Let f(a) = vac + 17 . We will use the definition of derivative to find the derivative of f (a). (i) What is the definition of derivative of f (a) ? Of' (x) = lim f(ath)- f(z) h -0 h Of' (x) = lim f(ath) - f(x-h) h-0 h Of' (2) = lim f(x+2 h) -f(ath) 2 h Of' ( 2 ) = f(ath) - f(ac) h (ii) Which one is the correct statement (the next step to find f (a) by definition)? Of'(2) = Vath+ 17 - vx +17 h Of'(2) = lim Vx+ 17 th - Vx +17 h -0 h Of' (x) = lim Vath+ 17 - Vac +17 h Of (2) = lim Vath+17 - Vac-h+ 17 h-0 h(iii) Which one is the correct statement (the next step to find f (x) by definition)? Of (x) = lim h h Oh(vath+17 - va+17) Of' (x) = lim 2h h Oh(vac + h+ 17+ vx+17) Of'(x) = lim h Oh(vx +h+17+ vac+17) Of(x) = lim h h Oh( vx + h+ 17 + vac+17) (iv) Which one is the correct statement (the next step to find f (a) by definition)? Of(20 ) = 1 2Va + 17 Of' (20) = 2 Vac + 17 17 Of (20 ) = 2va + 17 1 Of (2) =
