Which value of A in the exponential function would cause the function to stretch? f of x is equal to A times 1 third to the x th power

In f(x) = A(1/3)^x, A multiplies every output, so it controls a vertical stretch or compression. A vertical stretch occurs when |A| is greater than 1; among the choices, 1.5 is the only value greater than 1. Therefore, the function stretches when A is 1.5.
