Crescimento da função exponencial

Synopsis: a way to evaluate the growth of a function, both qualitatively and quantitatively, is the slope of the tangent line to the graph of the function at a point of the curve. With the cursor, change the power of the base value. Move the point P on the graph of the exponential function and observe the slope of the tangent line at P.
