For the function f(x) = 2x , make a table of slopes of secant lines and make a conjecture about the slope of the tangent line at x = 2. Complete the table. (Do not round until the final answer. Then round to the nearest thousandth as needed.) Interval Slope of the Secant Line [1, 2] [1.5, 2] [1.9, 2] [1.99, 2] [1.999, 2] It can be conjectured that the slope of the tangent line at x = 2 is (Round to the nearest integer as needed.)
