Question:

Suppose that k = 2.0, V0 = 50, and V* = 80. Write and graph the function giving output in terms of input as a function defined in pieces.
Suppose a neuron has the following response to inputs. If it receives a voltage input V greater than or equal to a threshold of V0, it outputs a voltage of kV for some constant k. If it receives an input less than the threshold value of V0, it outputs a fixed voltage V*.
