Follow the seven step strategy to graph the following rational function. f(x) = \frac{4x}{x^2 - 4} Find the horizontal asymptote(s). Select the correct choice below and, if necessary, fill in the answer box to complete your choice. A. The equation(s) of the horizontal asymptote(s) is/are . (Type an equation. Use a comma to separate answers as needed.) B. There is no horizontal asymptote. Plot points between and beyond each x-intercept and vertical asymptote. Find the value of the function at the given value of x. x -7 -5 -1 1 6 8 f(x) = \frac{4x}{x^2 - 4} (Simplify your answers.) Use the information obtained in the previous steps to graph the function between and beyond the vertical asymptotes. Choose the correct graph below.

Consider a generic psychrometric system with one inlet (state 1) and one exit (state 2) for moist air. The system includes one saturated liquid injection (state 3) at some temperature and two condensate removal sections at other temperatures (states 4 and 5). If a cooling coil is used within the system, derive an expression for: (20 pts) i. $m_a$ in terms of $\omega_1$, $\omega_2$, and each $m_i$ (using water mass balance) ii. Q in terms of $h_1$, $h_2$, $\omega_1$, $\omega_2$, and each $m_i$ and $h_f$ (using energy balance)
