Let f(x) = 2 x - 1 (a) Use a table of values to evaluate f(x) answers to one decimal place.) f(x) X x 1 and consider the limits lim f(x) and lim f(x). x-1 x+1+ 0.5 0.9 0.99 0.999 0.9999 0.99999 lim f(x) = lim f(x): x-17 2 x X 1.5 1.1 - 1.01 1.001 1.0001 1.00001 (b) Use an analytical argument to find each limit. (If the limit is infinite, enter 'co' or '-co', as appropriate. If the limit does not otherwise exist, enter DNE.) for values of x that approach 1 from the left and from the right. (Round your 1 f(x)
