Answer:
It is growth and the percentage rate of increase is 7.5%
Step-by-step explanation:
The exponential equation is as follows;
y = 550(1.075)^x
Now, I can identify that the exponential equation is that of growth.
This is because what is in the bracket i.e can be represented as 1+ 0.075
The 0.075 represents the margin of increase as we move on from one value to another
The percentage rate can be gotten by expressing 0.075 as a percentage
That would be expressing is as a fraction
This is just 7.5/100 which means what we have is 7.5%
It would be 1200 multiplied by 16 and the answer is 19,200
y = k/x
We want to find k first.
4 = k/8
4(8) = (k/8)(8)
32 = k
We now need to find y knowing that k = 32 and x = 2.
y = k/x
y = 32/2
y = 16
