Consider the following piecewise-defined function.\\ $f(x) = \begin{cases} 4x + 4 & \text{if } x < -4\\ \frac{1}{3}x - 5 & \text{if } x \ge -4 \end{cases}$\\ Step 2 of 3: Evaluate this function at $x = -4$. Express your answer as an integer or simplified fraction. If the function is undefined at the given value, indicate\\ "Undefined".\\ Answer\\ Selecting a radio button will replace the entered answer value(s) with the radio button value. If the radio button is not selected, the entered answer is used.\\ f(-4) = \underline{\qquad} \quad \circ \text{ Undefined}

Two electric charges are fixed in positions along the x-axis. q1 = 5.6 µC is located at x? = 0 cm and q2 = -6.5 µC is located at x2 = 7 cm. A particle with mass m = 18 mg and charge q = -3.1 µC is released from rest at point A where x = 23.5 cm. A The particle moves under the influence of the net electric field of q? and q? to point B a distance of d = 8.1 cm. What is the position on the x-axis of point B? x_B = 31.6 cm. B. What are the net electric potentials at points A and B? V_A = -69091.92 V V_B = -32273.708 V C. What is the speed of the particle upon reaching point B? v_B = 122.6 m/s
