Exercise 3: A system has a transfer function \frac{X(s)}{R(s)} = \frac{(15/z)(s + z)}{s^2 + 3s + 15} Plot the response of the system when R(s) is a unit impulse and unit step for the parameter z=3, 6 and 12. Exercise 4: Consider the differential equation \ddot{y} + 4\dot{y} + 4y = u where y(0) = \dot{y}(0) = 0 and u(t) is a unit step. Determine the solution analytically and verify by co-plotting the analytical solution and the step response obtained with 'step' function.

1-8 Produce graphs of \(f\) that reveal all the important aspects of the curve. In particular, you should use graphs of \(f'\) and \(f''\) to estimate the intervals of increase and decrease, extreme values, intervals of concavity, and inflection points. 1. \(f(x) = 4x^4 - 32x^3 + 89x^2 - 95x + 29\) 2. \(f(x) = x^6 - 15x^5 + 75x^4 - 125x^3 - x\) 3. \(f(x) = x^6 - 10x^5 - 400x^4 + 2500x^3\) \(x^2 - 1\) 4. \(f(x) = \frac{x^2 - 1}{40x^3 + x + 1}\) \(x\) 5. \(f(x) = \frac{x}{x^3 - x^2 - 4x + 1}\) 6. \(f(x) = \tan x + 5 \cos x\) 7. \(f(x) = x^2 - 4x + 7 \cos x, \quad -4 \le x \le 4\) \(e^x\) 8. \(f(x) = \frac{e^x}{x^2 - 9}\) 9-10 Produce graphs of \(f\) that reveal all the important aspects of the curve. Estimate the intervals of increase and decrease and inter- vals of concavity, and use calculus to find these intervals exactly. 9. \(f(x) = 1 + \frac{1}{x} + \frac{8}{x^2} + \frac{1}{x^3}\) 10. \(f(x) = \frac{1}{x^8} - \frac{2 \times 10^8}{x^4}\)
