SOLUTION
Given the question in the image, the following are the solution steps to answer the question.
STEP 1: Explain the given piecewise function
We look for where x is greater than zero and f(x) will be x
Where x equals 0 and the f(x) will be -1
Where x is less than 0 and f(x) will be -3
Hence, the correct graph will be:
