Question

Main Idea: To evaluate an exponential growth or decay function, substitute a value for the exponent variable and simplify.

Answer 1

Hey there!

In order to do this, we can just plug in 1 where it says t. It's exponential decay because the decay factor is less than one. We have:

f(t) = 2 * (1/2)^3 =
2* 1/2 * 1/2 * 1/2 =
2 * 1/8 =
2/8 =
1/4

Hope this helps!
