Thus graphs of exponential functions have horizontal asymptotes. c For very high x-values, f(x) moves toward the horizontal asymptote. Using the leading coefficient and the degree of the polynomial, we can determine the end behaviors of the graph. When the base of an exponential function is greater than 1, a large positive exponent will cause the entire expression to be very large, and a large negative exponent will cause the entire expression to be very small (although still positive). The basic result is: in a race to inﬁnity, exponential functions come in ﬁrst, followed by power functions, and logarithmic functions are in last place. What is the End behavior on the right side.
