Question

Use the function below to find F(1).

f(t)=4*(1/2)^3t
A. 5/8
B. 1/4
C. 2/3
D. 1/2

Answer 1

Answer:
`(1)/(2)`

Explanation:

The given function :
`f(t)=4*((1)/(2))^(3t)`

To find f(1) means to find the value of
`\text{f(t)}` when t=1, we need to substitute the value of t in the given function, then we get

`f(1)=4*((1)/(2))^(3*1)\\\\\Rightarrowf(1)=4*((1)/(8))\\\\\Rightarrowf(1)=(1)/(2)`

Hence, the value of
`\text{f(t)}=(1)/(2)`

Answer 2

The correct answer is D.
4 * (1/2)^3
4 * (1/8)
4/8 = 1/2
