Determinați domeniul de definiție al funcției f: d→r, f(x)=(√2-3x)+2

The domain is all real numbers less than or equal to two-third

Step-by-step explanation:

The question in English is

Determine the domain of the function f :D→R,

we know that

The radicand of the function must be greater than or equal to zero

so

Solve the inequality for x

subtract 2 both sides

Multiply by -1 both sides

Divide by 3 both sides

The solution is the interval ----> (-∞,2/3]

therefore

The domain is all real numbers less than or equal to two-third
