Which is the graph of f(x)=√x?
djverab [1.8K]

Answer:

Given function:

f(x)=\sqrt{x}

Replace f(x) for y:

\implies y=\sqrt{x}

Square both sides:

\implies y^2=x

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

If we square root this again, we get:

\implies \sqrt{y^2}=\sqrt{x}

\implies y=\pm\sqrt{x}

So y=\sqrt{x} is the part of the parabola in quadrant I → (x, y)

And y=-\sqrt{x} is the part of the parabola in quadrant IV → (x, -y)

(Refer to attachment 2)

Therefore, the graph of the given function is <u>attachment 3</u>.
