1. Using fix point representation with 1 bit for the sign, 7 bits for the integer part, and 5 bits for the decimal part, what is the binary representation of 20.5?
2. Using sign and magnitude representation, what is the binary representation of -25 if you use 7 bits in total?
3. Consider the function f(x) = -x^3+2x^2+x-2

By using Simpson's Rule 1/3 (single application), calculate the estimated value of the integral of f(x) from x = -1 to x = 2rounded to 2 decimals
