Question

I'm doing domain and range, and I'm kinda having a hard time with this... can someone help?

Answer 1

`\boxed{\sf Option \ A}`

Explanation:

`y=x^2`

`\sf The \ domain \ of \ a \ function \ is \ all \ possible \ values \ for \ x.`

`\sf There \ are \ no \ restrictions \ on \ the \ value \ of \ x.`

`\sf The \ domain \ is \ all \ real \ numbers.`

`\sf The \ range \ of \ a \ function \ is \ all \ possible \ values \ for \ y.`

`\sf When \ a \ number \ is \ squared \ the \ result \ is \ always \ greater \ than \ or \ equal \ to \ 0.`

`\sf The \ range \ is \ \{y:y\geq 0\}`

Answer 2

Domain : any real number

Range : y ≥0

Explanation:

The domain is the values that x can be

X can be any real number

The range is the values the y can be

Y can be zero or any positive value since y = x^2

Domain : any real number

Range : y ≥0
