Answer:
f(5) = 11 and 1/3, or approx. 11.33
Step-by-step explanation:
[tex]f(x) = 2x + \frac{4x}{3x}[/tex]
We can divide away x in 4x/3x:
[tex]f(x) = 2x + \frac{4}{3}[/tex]
To calculate f(5), we substitute x with 5:
[tex]f(5) = 2 * 5 + \frac{4}{3} = 10 + \frac{4}{3} = 11 \frac{1}{3}[/tex]
Answer: 11 and 1/3, or approx. 11.33
