There will be two pieces. The graph indicates that x = −0.5 is the boundary point.

Does the slope from the left of x = −0.5 appear to agree with the slope from the right?

Find the derivative of each piece of your piecewise function.
Then evaluate these limits. Do they agree?

Notice Hana's definition of the derivative! This question is asking f '(−0.5) from the left agrees with f '(−0.5) from the right.
Looking at the graphs, do the slopes appear to agree from both sides of −0.5?
