10 Use the graph of /(X) above to answer the following questions. You can answer using a list of multiple values by separating the values with commas List all T-values for which f (2:) is undefined. f(z) undefined at I f (a) is defined for all values of I List all values c - a at which lim / (1) does not exist. " The limit does not exist at ar The limit exists at all values of I. List all -values at which / is discontinuous Function f is discontinuous at a HFunction f is continuous at all values of c
