<u>Answer:</u>

Initial value: 250
Decay
Decay rate: 11%

Initial value: 40
Growth
Growth rate: 11%
<u>Step-by-step explanation:</u>
The function we have on the left of the table is:

<u>Initial value</u> (when x = 0): 
y = 250 (initial value)
Growth or Decay: 0.89 < 1 so decay
Decay rate: (1 - 0.89) * 100 = 11%
Function on right side:

<u>Initial value</u> (when x = 0): 
y = 40 (initial value)
Growth or decay: 1.11 > 1 so growth
Growth rate: (1.11 - 1) * 100 = 11%
Answer:
Domain is R ( all real numbers)
Range is R (all real numbers)
Answer:
There is one solution
Step-by-step explanation:
15x+11=8x
Subtract 15x from each side
15x-15x +11 = 8x-15x
11 = -7x
Divide by -7
11/-7 = -7x/-7
-11/7 =x
