and wish to find a y-value corresponding to an x-value between those x-values in the table, assume the (unknown) function y = f(x) is locally linear and use linear interpolation. Use the following equation, where x1 and x2 bracket x.: y = y1 + E.g. find f(5.8) = 25.2 + (25.8-25.2)(5.8-5)/(6-5) = 25.68. Step functions ................
