A graph of y = Rx) is shown and a c-value is given. Use the graph to find the following, whenever they exist. (If the limit is infinite, enter '00' or '-00', as appropriate. If the limit does not otherwise exist, enter DNE. ) c = 20 y = Rx) -20 10 O - 10 10 20 30 -10 (a) lim Rx) b) f(c) -/3.4 Points] DETAILS HARMATHAP12 9.1.013. Complete the table and predict the limit, if it exists. (Round your answers to three decimal places. If the limit is infinite, enter 'co' or '-co", as appropriate. If the limit does not otherwise exist, enter DNE.) *(x) = 6x - 1 for x
