Answer:
100/9 ≈ 11.11...(repeating)
Explanation:
You want the maximum value of 0.3^x on the interval [-2, 2].
Decreasing
The base of 0.3 is less than 1, so you know the function is decreasing. The maximum value will be at the left end of the interval, where x = -2.
y = (0.3)^-2 = 1/0.09 = 100/9 ≈ 11.11...(repeating)
