for the columns where is less than or equal zero, use the first line of the function to calculate the value of f(x)

{ ( \frac{1}{3} ) }^{ - 2} - 1  = 9 - 1 = 8 \\ { ( \frac{1}{3} ) }^{ - 1}  - 1 = 3 - 1 = 2 \\ { ( \frac{1}{3} ) }^{ 0} - 1  = 1 - 1 = 0

for every x greater than zero, use the second line to determine the value

{3}^{1}  - 2 = 3 - 2 = 1 \\ {3}^{2}  - 2 = 9 - 2 = 7

hope this helps and gives some insight what to do.

if there are open questions left, feel free to ask them in the comments

have a beautiful day

Answer:

I dont really understand this notation, but it should be C or D. If the inequality includes 2, its C. If it doesn't include its D. Most likely it includes im guessing but Im not sure. So if you know how this notation works, its C or D. C for including 2 and D for excluding 2.

<h2><u>Answer: Probably C but can be D</u></h2>
