On a coordinate plane, an exponential function that has a horizontal asymptote of y = 0 is shown. The function has points (negative 2, StartFraction 4 Over 81 EndFraction), (negative 1, two-ninths), (0, 1), (1, nine-halves), (2, StartFraction 81 Over 4 EndFraction)
What is the multiplicative rate of change of the exponential function shown on the graph?

Two-ninths
1
4
Nine-halves

Multiply-by 9/2 (9/2).

Reason: y(0) = 1 so y = b^x. Then b = y(1)/y(0) = (9/2)/1 = 9/2, which matches the other points.
