Question

The number of subscribers y to a website after t years is shown by the equation below.

Answer 1

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 2

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 , $y=50(1.75)^t$ 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

$y=50(1+0.75)^t$

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.
