A.) Mark is correct as every increase in x of 2 equals a y increase of 4
100-32=68 because 32% and 32 puppies 1 puppy for each percent and take away those puppies from 100 that’s your answer
For each increment in x, the output is multiplied by 2. The function could be written the way a geometric sequence can be written:
... f(x) = 5·2^(x-1)
Or, it could be simplified to ...
... f(x) = (5/2)·2^x
The first 5 terms will be
... 5, 10, 20, 40, 80
