Question

find Domain f(x)=2√x - 3 please tell​

Answer 1

Domain of a function is defined as the set of all real numbers for which the given function is defined.

Now, according to the question:

f(x) = 2√x - 3

Thus, for f(x) to be real: √x must be defined.

That is, x > 0

Hence, domain of f(x) is x > 0 or x € [0,∞).
