What is the significance of taking a derivative when you have to have the information to plot a graph accurately to begin with?

    The derivative is the slope of the tangent to the curve. It's a useful tool to find what are called maxima, minima and "turning points" on the curve (the points at which the curve has tangents that are parallel to the x-axis.

    Usually, your graph is based on a function, rather than a series of points. Most functions that are used are continuous and differentiable, and not have singularities (or holes)

    Speed - you can instantly get the turning points without plotting the whole graph. Also, where the function is increasing or decreasing.
