Unformatted text preview: g ( x ) = ( x + b if x < cos x if x ≥ . (a) Is there a choice of b that will make g ( x ) continuous at x = 0? Why or why not? (b) Is there a choice of b that will make g ( x ) diﬀerentiable at x = 0? Why or why not? 3. Assume that g (3) =-1, h (2) = 5, and h (2) = 3. If f ( x ) = ( g ◦ h )( x ), what is f (2)? 1...
