2. Assume f(1)=10, f'(x)>=2 for 1<=x<=4, now describe the smallest value that f(4) would be Assume that f is invertible and differentiable on an open interval I with inverse g. Which of the following statements is not always true? f(a) and g'(b) ƒr (b) b. If f'(a) #0 then g is differentiable at b = f(a) and g'(b) = f'(a). c. If ƒ'(a) ‡ 0 then L is invertible and (L£)−¹ = L² where b = f(a). d. None of the above a. If ƒ'(a) ‡ 0 then g is differentiable at b = = 2
