Question

Can someone explain how to do this please?

Answer 1

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

`{ ( (1)/(3) ) }^( - 2) - 1 = 9 - 1 = 8 \\ { ( (1)/(3) ) }^( - 1) - 1 = 3 - 1 = 2 \\ { ( (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
