Problem 1) Use MATLAB commands to compute the zeros of the following function y(x), over the range -10 < x < 10.
y(x) = 3x3 - 12x2 - 33x + 80
Problem 2) Use a loop in MATLAB to determine how long it will take to accumulate $1,000,000 in a bank account if you deposit $10,000 initially and $10,000 at the end of each year; the account pays 6 percent annual interest.
Problem 3) The following functions describe the oscillations in electric circuits and the vibrations of machines and structures. Plot these functions on the same plot. Because they are similar decide how best to plot and label them to avoid confusion.
y(t)=7e^(-.4t)cos(5t-3)
x(t)=10e^(-.5t)sin(3t+2)
