Question

F(x)=sqrt X
How do I find domain and range? Please and Thank you.

Answer 1

\[f(x)equals \sqrt{x}\]

Answer 2

For Domain of Square root numbers always remember that the square root values should be greater or equal to zero but it can't be negative..

\[x \ge 0\]

So Domain is all positive real numbers including 0 also..

But no negative numbers..

Answer 3

So the range would be [infinity, 0)?

Answer 4

NO..

Answer 5

let f(x) = y

so,

y = \(\sqrt{x}\)

Square both the sides:

\(y^2 = x\)

Range is (infinity, -infinity)..

Answer 6

Sorry:

(-infinity, infinity)

Answer 7

Thank you.

Answer 8

Welcome dear..
