You can use your TI-84 Plus calculator to find the zeroes of a function. The zeros of the function y = f(x) are the solutions to the equation f(x) = 0. Because y = 0 at these solutions, these zeros (solutions) are really just the x-coordinates of the x-intercepts of the graph of y = f(x).
How does a calculator always know the answer?
Like all other electronic devices, calculators work by processing information in binary form. Thus, when you input numbers into a calculator, the integrated circuit converts those numbers to binary strings of 0s and 1s.
