Answer:

Step-by-step explanation:

B. 9^2
explanation: 3^4 is equivalent to 3*3*3*3, which is 81
9^2 (9*9) also equals 81
The domain is all real numbers
The Range is y > 0
AS x increases by 1 the value of y is 1/7 of previous value
2x - 1 = 9 - 14x
16x - 1= 9
16x = 10
x = 10/16
x= 5/8 is the answer
