Determine whether each statement is true or false. You have one submission for each statement. (a) For all functions \(f\), if \(f\) is continuous on the interval \([a, b]\), then \(f\) has an absolute maximum value and an absolute minimum value on the interval \([a, b]\). True False (b) The function \(\frac{-3x^3 - 7x^2 - 6x + 590}{x - 5}\) has an absolute maximum value and an absolute minimum value on the interval \([4, 7]\). True False (c) The function \(\frac{-3x^3 - 7x^2 - 6x + 590}{x - 5}\) has an absolute maximum value and an absolute minimum value on the interval \([9, 13]\). True False

3) [25] A proton moves in a circle in the $x - y$ plane with a speed of 280 m/s through a uniform magnetic field of 2.0 T, which is in the $-\hat{z}$ direction. a) What is the orbital radius? b) Make a sketch of the situation and indicate whether the motion is clockwise or counter- clockwise when viewed from the top (bird's view from a point at positive $z$).

6. Stimulus intensities are mainly encoded in the primary afferent neuron by: a. The size of the action potential b. The length of the action potential c. The size of the receptor potential d. The amount of neurotransmitter released into the CNS 7. Including both direct and indirect effects, which of the following has the largest impact on differential ion concentrations in the intracellular vs extracellular fluid: a. Voltage-gated Na$^+$ channels b. Na$^+$/K$^+$ ATPase pump c. Voltage-gated Ca$^{2+}$ channels d. Na$^+$ leak channels 8. Which of the following is NOT true about the relative refractory period? a. It begins while voltage-gated Na$^+$ channels are activated b. Another action potential can be triggered c. It is due to hyper-polarization d. It begins while voltage-gated K$^+$ channels are open 9. Two separate post-synaptic interneurons receive synaptic potentials from afferent neurons in the periphery. The dendrites of one these interneurons receive two excitatory post-synaptic potentials (EPSP) and two inhibitory post-synaptic potentials (IPSP) of equal magnitude at the same time. The dendrites of the other interneuron receive four excitatory post-synaptic potentials that are the same sized as the EPSPs and IPSPs received by the other interneuron. The mostly likely outcomes is... a. The interneuron receiving only the EPSPs fires an action potential b. Both interneurons fire an action potential c. The interneuron receiving both the EPSPs and IPSPs fires an action potential d. Neither interneuron fires an action potential
