B. 455421.123 many member will there be after 4 year
What is an exponential function?
A mathematical function with the formula f (x) = an x is an exponential function. where an is a constant known as the function's base and x is a variable. The transcendental number e, or roughly 2.71828, is the exponential-function base that is most frequently seen.
When b > 0 and b 1, an exponential function has the form f(x) = bx. The base is b, and the exponent is x, just as in any exponential equation. The development of bacteria is an illustration of an exponential function. Some germs multiply by two per hour.
Given that,
members = 300000
member increased by 11%
an exponential function that represent the webite membership after t year:
y = [tex]a(1+r)^t[/tex]
member will there be after 4 year:
y = [tex]300000 (1+0.11)^4[/tex]
y = [tex]300000 (1.11)^4[/tex]
y = 455421.123
