### What’s up with a cusp?

Today, students will identify points of non-differentiability and check to see if:

Continuity and Differentiability
• Explain why a function must be continuous at x=c to be differentiable at x=c. The graph below might help you.
Using the definition of derivative:
• Use the definition of the derivative as a limit to find the slope function f’(x) of f(x)=4x2-3. Then use your slope function to find f’(11) and f’(1000).
