The range is [0, +oo)
.................................

Answer 2

Answer:

The range of the function is [0,∞) or y≥0.

Step-by-step explanation:

The given function is

$y=x^2$

Domain is the set of all possible input and range is the se t of all possible outputs.

We the value of y is equal to the square of x. We know that the square of any real number is always positive.

$x^2\geq 0$

$y\geq 0$

It means the value of y is always greater than or equal to 0 for any real value of x. So, the range of the function is all positive real numbers including 0.

Range = { y | y≥0, y∈R}

Range = [0,∞)

Therefore the range of the function is [0,∞) or y≥0.
