Answer:

The value of f(3) is 5.85

Step-by-step explanation:

The given function is [tex]f(x)=\frac{8}{1+3e^{-0.7x}}[/tex]

In order to find the value of f(3), we substitute x = 3 in given function f(x).

[tex]f(3)=\frac{8}{1+3e^{-0.7\cdot3}}[/tex]

Simplify the exponent of e

[tex]f(3)=\frac{8}{1+3e^{-2.1}}[/tex]

Now, find the value of the denominator

[tex]f(3)=\frac{8}{1.36736928476}[/tex]

Finally, simplify the fraction

[tex]f(3)=5.8506506539[/tex]

Rounded to the nearest hundredth, we have

[tex]f(3)=5.85[/tex]
