what is the domain of the function Y= square root 2x+10 explain and show work ) A. X≥5 B. Y≥5 C. X≥-5 D. Y≤-5 ​
Anna [14]

Solution: x ≥ -5

<h2>Steps</h2>

Domain Definition: The domain of a function is the set of input or argument values for which the function is real and defined

<u>squareroot 2x + 10</u>  ⇒  <u>2x + 10 ≥ 0</u>

Solve 2x + 10 ≥ 0:

Subtract 10 from both sides

2x + 10 - 10 ≥ 0 - 10

Simplify

2x ≥ -10

Divide both sides by 2

2x / 2  ≥  -10 / 2

Simplify

2x / 2

Divide the numbers: <u>2 / 2 = 1</u>

= x

Note: x has the same value as 1

Divide the numbers: -10 / 2 = -5

= -5

The function domain is

x ≥ -5
