Non-calculator (except where indicated). Be sure to show the work and provide explanations to support your answers! 1. Evaluate each limit: 3x lim x-5 x2 + 1 x - 1 lim X-1 x2 + 2x - 32. Use a calculator to complete the table of data values; then use the table of values to determine the limit: x3 - 2x2 + 4x - 8 lim X-2 x2 + x - 6 Explain. X 1.9 1.99 1.999 2 2.001 2.01 2.1 Yx3-125 3. Identify any removable and any non-removable discontinuities of the function f(x) = X2-25' explaining how you determine these algebraically and what they look like on the graph of f(x)
