Answer:
So the multiplicative rate of change is increased by a factor of 5 per 1 unit increase in x.
Step-by-step explanation:
I think your function is off... but I can look at your ordered pairs.
(1,10)
(2,50)
(3,250),..
As the x increases by 1 the y is being multiply by a factor of 5 each time.
So the multiplicative rate of change is increased by a factor of 5 per 1 unit increase in x.
