Final answer:
Yes, the equation y = -2(4^x) represents an exponential function.
Step-by-step explanation:
An exponential function is a function of the form y = abx, where a and b are constants and x is the variable.
In this case, a = -2 and b = 4, so we have y = -2(4x), which is in exponential form.
Therefore, the equation y = -2(4x) represents an exponential function.
In an exponential function, the variable x appears as an exponent, and the graph of the function forms a curve that either increases or decreases without bound as x increases or decreases.
