Answer:
[tex]y=400,000(1.32)^t[/tex]
Step-by-step explanation:
Equations for exponential growth are of the form
y = a(1+r)ˣ, where a represents the initial amount, r represents the percent of growth per year and x represents the amount of time.
In this case, the site currently has 400,000 members; this is our value for a.
The growth is expected to be 32% per year; 32% = 32/100 = 0.32; this is r.
We are using t for time.
This gives us
[tex]y=a(1+r)^x\\\\y = 400,000(1+0.32)^t\\\\y = 400,000(1.32)^t[/tex]
