Drawing a parabola

To draw a parabola (y=x**2):

import matplotlib.pyplot as plt

x = np.linspace(-10, 10, 1000) # Domain from -10 to 10 with 1000 data-points
plt.title("Parabola $y=x^2$")
plt.xlabel("$x$", fontsize=14)
plt.ylabel("$y$", fontsize=14)
plt.plot(x, x**2)

The output is as follows:

Helper function to draw functions

def my_func(x):
return x**2

def plot_function(x_lim, my_func):
"""
@param x_lim {Array} an array of size two that contains the lower and upper x limits
@param my_func {Function} the function that we want to plot
"""
x = np.linspace(x_lim[0], x_lim[1], 1000)
plt.xlabel("$x$", fontsize = 14)
plt.ylabel("$y$", fontsize = 14)
plt.plot(x, my_func(x))

We can use plot a curve like so:

plot_function([-10,10], my_func)

The output is as follows:
