Use the limit definition to find the slope of the tangent line to the graph of f at the given point. See Examples 3, 4, and 5. f(x) = 4; (3, 4) Step 1 Recall that the slope of a secant line on a graph from a given point, x, to some point that is Ax away from x is given by the following. f(x + Ax)-f(x) Ax m sec The slope of the tangent line at the point x is then found by taking the limit of the slope of the secant line as A → 0. We will first determine msec for f(x) = 4 at the point (-3, 4). = = m sec = 4 f(x + Ax)-f(x) Ax f(-3 + Ax)-f( [ Ax Ax
