What does roots mean in math?
A root is a value for which a given function equals zero. When that function is plotted on a graph, the roots are points where the function crosses the x-axis. For a function, f (x), the roots are the values of x for which f (x) = 0. For example, with the function f (x) = 2−x, the only root would be x = 2,…
