Create a function file named Func01_p4.m which has 4 arguments: x, a, b, and c. The independent variable being x of the function below:
Y = ax^2+bx+c
Download the data04_02.txt from the course website. This file consists of 3 space-­‐delimited integers. In your main script file, store these integers into the respective variables: a, b, and c. These will be the coefficients of the 2nd degree polynomial you will be integrating. Any time you refer to @Func01_p4 make sure you use the appropriate arguments (a, b, and c).
Display the polynomial like you were writing an equation (see below):
(7)*x^2 + (1)*x + (3)
where 7, 1, and 3 are the coefficients a, b, and c respectively that you imported from the file (which are different from these coefficients).
I got the part where it asks to store the integers into respective variables, but I don't get what it means by Display the polynomial like you were writing an equation.

you can do something like this:
fprintf('(%d) * x^2 + (%d) * x + %d\n', a, b, c)

just one more question. Where did you get the "n"?

'\n' mean new line. so after executing fprintf command the cursor goes to next line on the command window. Fpr more infomation you can see:
