Answer:
The fourth graph.
Step-by-step explanation:
We have f(x + 1) so the x values will be increased by 1.
first value = 108 (when x = 1)
next value = 108 * 2/3 = 72 (when x = 2)
next = 72 * 2/ 3= 48 (when x = 3)
next = 48 * 2/3 = 32 (when x = 4)
Answer:
B.
Step-by-step explanation:
First, notice that we can cancel out an x in the second term. Thus:

As with the last question, change the sign to multiplication and "flip" the second term:

Multiply straight across:

Cancel the (x+1) term:

Cannot be simplified further.
B.
Answer:
