Exponential growth and decay functions are written in standard form as
f(t) = a0•b^kt , where ao is an initial amount, b is the growth factor, k is the
growth rate, and t is

Option c.

Step-by-step explanation:

Exponential growth and decay functions are written in standard form as  

.......... (1)

where is an initial amount, b is the growth factor and k is the growth rate.

We have to say what t denotes in the equation (1) and choose from the given options.

I think t denotes the time in this equation, hence, option c will be correct. (Answer)

practice. practice. practice.

wait nvm i know the correct answer now its 100%   81 square feet
