Question

Find the domine of y=√(2x + 3)​

Answer 1

The range is the set of values that correspond with the domain.
Domain:
[
−
3
2
,
∞
)
,
{
x

Answer 2

Answer:

Explanation:

Given :

• Fuction, y = √2x + 3

To Find :

• Domain.

Solution :

Fuction, y = √2x + 3

⇒√2x + 3

⇒2x + 3

⇒ x ≥ -3/2

⇒ x € R

⇒x € [ -3/2 , +∞ ]

Hence, Domain is [ -3/2 , +∞ ].
