Final answer:
The exponential function has no intercepts because it grows or decays exponentially.
Step-by-step explanation:
The function that has no intercepts among the given options is the exponential function (c). An exponential function is of the form y = a^x, where a is a positive constant and x is the input variable. The graph of an exponential function never intersects the x-axis because the function grows or decays exponentially, depending on whether the base a is greater than 1 or between 0 and 1, respectively.
