Solve the problem.Can anything be said about the graph of a function y = f(x) that has a second derivative that is always equal to zero? Give reasons for your answer.
What will be an ideal response?
The graph will be a straight line. Since y'' = 0, this means there is no change in y', which is the slope of y. A constant slope implies a straight line.
