Question 1. Go to random.org. This website is a random number generator. Use it to generate three numbers a, b, c between -10 and 10. Now let your a, b and c be the coefficients of the quadratic function f(x)=ax2 +bx+c. (For example, if the numbers you generated happened to be a = 2,b = 12, c = −1, your function for the rest of the question would bef(x) = 2x2 +12x−1.) (a) Put f(x) into “standard” or “vertex” formf(x)=a(x−h)2...

The first random number generator comes from Python itself. To use it you need to import the Python package. Then call the random() method. See below. import random print (random.random()) It is important to know that a random number generator really is random. If so, it should have uniform distribution between 0 and 1. Test the random number generators in Python for uniformity.
