$g(x) \frac{3x}{x^{2}-81} \\ \\ D: x^{2}-81 \neq 0 \\ \\ (x-9)(x+9) \neq 0 \\ \\ x-9 \neq 0 \ \vee \ x+9 \neq 0 \\ \\ x \neq 9 \ \vee \ x \neq -9 \\ \\ x\in R \ \setminus \lbrace -9,9 \rbrace \\ \\ x\in (-\infty,-9) \ \cup \ (-9, 9) \ \cup \ (9,+\infty)$

Let's say H=height and A=age.

so 1.6a=h

example, if the plant was 5 years, months, etc. it would be

1.6(5)=8
