Analyze the function 1 x + 13 if x < 4 2 4 x +11 if x 24 Your classmates may be analyzing different functions, so in your initial post in Brightspace be sure to specify the function that you are analyzing. Part 1: Is continuous at 4? Explain why or why not in your Discussion post O Yes O No Hint: In order forf@) to be continuous at x = 4, the limits off@) from the left and from the right must both exist and be equal to f Part 2: Is f@) differentiable at x = 4? Explain why or why not in your Discussion post. O Yes O No Hint: Similarly to continuity, in order for f (x) to be differentiable at x = 4, f@) must be continuous at from the left and from the right must both exist and be equal to each other. 4 and the limits of the difference quotient
