Answer
Explanation:
Step1: Correct the function form
Assume the function is $g(x) = \left(\frac{1}{9}\right)^x$ (standard exponential form).
Step2: Calculate $g(-2)$
Use negative exponent rule: $a^{-n}=\frac{1}{a^n}$ $g(-2) = \left(\frac{1}{9}\right)^{-2} = 9^2 = 81$
Step3: Calculate $g(-1)$
Apply negative exponent rule $g(-1) = \left(\frac{1}{9}\right)^{-1} = 9^1 = 9$
Step4: Calculate $g(0)$
Use zero exponent rule: $a^0=1$ $g(0) = \left(\frac{1}{9}\right)^0 = 1$
Step5: Calculate $g(1)$
Evaluate positive exponent $g(1) = \left(\frac{1}{9}\right)^1 = \frac{1}{9}$
Step6: Calculate $g(2)$
Evaluate positive exponent $g(2) = \left(\frac{1}{9}\right)^2 = \frac{1}{81}$
Answer:
| $x$ | $g(x)$ |
|---|---|
| $-2$ | $81$ |
| $-1$ | $9$ |
| $0$ | $1$ |
| $1$ | $\frac{1}{9}$ |
| $2$ | $\frac{1}{81}$ |
