think of 1.75 as 1+0.75
That's in the form 1+r where r is the growth rate.
So r = 0.75 = 75% is a growth rate
Answer:-It increased by 75% every year.
Explanation:-
Given: The number of subscribers y to a website after t years is shown by the equation , [tex]y=50(1.75)^t[/tex] where 50 is the initial number of subscribers to a website and t is the time period is years.
The above equation can be rewrite as
[tex]y=50(1+0.75)^t[/tex]
which is equivalent to the exponential growth function with growth rate r=0.75=75%
⇒ The number of subscribers to a website increased by 75% every year.
⇒ First option is correct.
