Left-most root Bisection method

How do i solve this? I need help in flowchart and coding. Create a function to determine the left-most root of the following equation using the Bisection Method:

\( f(x) = -x^{3} -3x + 9 \)

The input would be in the sequence, a, b, and error. Name the function "bisection_method(a, b, error)". The "a" is the lower bound, the "b" is the upper bound, and the "error" is the tolerance level. If there is no root then the display would be "no root".
