Domain: $x \in 9 - \infty, \infty)$ $x in 9-oo, oo)$
Range: $y \in 0, \infty)$ $y in 0, oo)$
y-intercept ( x = 0 ) is 2..

Continuous $y = 2 (3^{x}) > 0, \to 0$ $y=2 (3^x)>0 , to 0$ , as $x \to - \infty and \to \infty$ $x to -oo and to oo$ , as $x \to \infty$ $x to oo$ .

graph{y-2 3^x=0 [-7.89, 7.89, -3.946, 3.944]}
