1st and 2nd DifferencesQuadratic Functions have constant second differences. Second differences can be calculated by finding the rate of change with the first differences. Linear functions have constant first differences. Since quadratic functions do not have constant first differences, they do not have a slope that remains constant for the entire graph of a parabola.
