The following source code shows how to plot two mathematical functions (one linear and one quadratic) using the Matplotlib library, save the result to a PNG image, and display it on the screen. The functions are:
Quadratic: \(f_1(x) = 2x^2 + 5x - 2\)
Linear: \(f_2(x) = 4x + 1\)
This is the resulting image:
And the code:
The Matplotlib library required by this code can be installed via
python -m pip install matplotlib.
