Define the Mathematical Function in Python

This is the same mathematical function written in Python. It returns 2 * x + 80, where x is the input:

Example

def my_function(x):
return 2*x + 80

print (my_function(135))

Try replacing x with 140 and 150 in the function.

Plot a New Graph in Python

Here, we plot the same graph as before, but with the axis formatted differently. The maximum value for the y-axis is now 400, and for the x-axis, it is 150.

Example

import matplotlib.pyplot as plt

health_data.plot(x =‘Average_Pulse’, y=‘Calorie_Burnage’, kind=‘line’),
plt.ylim(ymin=0, ymax=400)
plt.xlim(xmin=0, xmax=150)

plt.show()

Example Explained

Import the pyplot module from the matplotlib library.
Plot the data by plotting Average_Pulse against Calorie_Burnage.
Use kind=’line’ to specify that we want a line plot.
Set the range for the y-axis and x-axis using plt.ylim() and plt.xlim(), respectively.
Display the plot with plt.show().
