Question 3 [40 marks] Write a program to draw a text-based graph of a mathematical function f(x). Use axis limits
of - 10 to 10 and only plot discrete points i. e. points with Integer value ordinates.
Sample I/O:
Enter a function f(x):
x+2
I
Use nested loops to print the entire area of the graph (i. e. an outer loop for rows and an
inner one for columns), keeping track of the current x and y values. Whenever the (rounded)
value of the function f(x), entered by the user, is equal to the current y value, output "*" (an
asterisk), otherwise, output either the appropriate axis character or a space.
NOTE: Remember to import math to enable the use of some mathematical functions.
How should the program support the entering of arbitrary functions?​
