= ax? + bx+c.
• Ask the user for the coefficients a, b and c of a quadratic function f (x)
• Output the results for x values of (0, 1, 2, .., 9), then x values of (10, 100, .., 10,000,000).
• You must write two functions:
1. A function that returns the value of the quadratic function given the coefficients and the value x.
2. A function that prints the value of the quadratic function given the coefficients and the value x. This function will call the first
function.
• You must use a for loop for the x values 0 to 9, and a while loop for the powers of ten.
