Question

f:R-> R, determinati valoarea raportului f(0)/2=?

Answer 1

Cum f(x) =4
Inlocuim x cu 0: f(0)=4
f(0)/2=4/2=2

Answer 2

[tex]f: \mathbb{R}\longrightarrow \mathbb{R} , \ f(x) = 4 \\\;\\ f(0) = 4 \Longrightarrow\ \dfrac{f(0)}{2} =\dfrac{4}{2} =2.[/tex]

Observatie:

Functia  f(x) = 4  este o functie constanta.
