F (x) = 20/4+3e-0.2x

What is f (3) ?

Enter your answer, rounded to the nearest tenth, in the box.

12.6

Step-by-step explanation:

Given the function, F (x) = 20/4+3e-0.2x

Where e is an exponential function,

To get f (3), we need to substitute x = 3 into the given function

F (3) = 20/4 + 3e - 0.2 (3)

f (3) = 5 + 3e - 0.6

f (3) = 4.4+3e

Substituting the value of e = 2.718

f (3) = 4.4+3 (2.718)

f (3) = 12.554

f (3) = 12.6 to the nearest tenth.
