Question

Which is the graph of f(x)=√x?

Answer 1

The Graph is in the picture above ;)

Answer 2

Given function:

`f(x)=√(x)`

Replace f(x) for y:

`\implies y=√(x)`

Square both sides:

`\implies y^2=x`

This is a sideways parabola that opens to the right, with an axis of symmetry at y = 0. (Refer to attachment 1)

If we square root this again, we get:

`\implies √(y^2)=√(x)`

`\implies y=\pm√(x)`

So
`y=√(x)` is the part of the parabola in quadrant I → (x, y)

And
`y=-√(x)` is the part of the parabola in quadrant IV → (x, -y)

(Refer to attachment 2)

Therefore, the graph of the given function is attachment 3.
