Answer:
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.
Answer:
If you has meant, 20/4+3e^-0.2x it would be 3.5
Step-by-step explanation:
20/4+3e^-0.2(x)
Plug in 3 for x
20/4+3e^-0.2(3)
20/4+3e^-0.6
e=2.7182818
20/4+3(2.7182818)^-0.6
20/4+8.15484548^-0.6
20/4+1.6464349
20/5.64643
3.54205810
Rounded to the nearest 10th
3.5
