### In a mathematical problem, Samuel was provided with the values of s, u, and a and the value of t was asked to be calculated. Samuel substituted those values into the second equation of motion and got a quadratic equation in t as a result. He thought of plotting a graph taking t in the x-axis. How will the graph look like?
