Let f(x) = Calculate ƒ(6+h)-f(6) f(x) - ƒ(6) x-6 and x h (Express numbers in exact form. Use symbolic notation and fractions where needed.) f(x)-f(6) = x-6 ƒ(6+h)-f(6) h Take the appropriate limit to find /'(6). (Give an exact answer. Use symbolic notation and fractions where needed.) f'(6)= Determine f'(a) for a = 2.5, 4, 7. y 5 4 3 2- 1 +X 1 2 3 4 5 6 7 8 9 (Give exact answers. Use symbolic notation and fractions where needed.
