1. Visualize the function graph with Python and find points where the curve intersects the X axis.

2. Find roots of an equation using a Python implementation the fixed-point iterations method.

Note: Functions in tasks 1 and 2 are the same. So, the function graph built in task 1 can help with

defining an initial point for the fixed-point iteration method.

3. Resolve the system of linear algebraic equations using the Python Numpy library.

4. Approximate the definite integral using the Scipy Python library.

1. f(x) = x2 3x + 1
