Calculate the difference quotients for f(x)=7−4x using h=0.1, 0.01, and 0.001. Use the results to approximate the slope of the tangent line to the graph of f(x) at the point (6,−17). If necessary, round the difference quotients to no less than six decimal places and round your final answer to two decimal places.
