For the following function, make a table of slopes of secant lines and make a conjecture about the slope of the tangent line at the indicated point. I f(x)=7cosxatx= Complete the table below. (Round the nal answer to three decimal places as needed. Round all intermediate values to four decimal places as needed.) Interval Slope of secant line An accurate conjecture for the slope of the tangent line is (Type an integer or a decimal.)
