Graph g(x)=1/6 square root of x

$g (x) = \frac{1}{6} \sqrt{x}$

Step 1

Find the domain for $y = \frac{1}{6} \cdot \sqrt{x}$ so that a list of $x$ values can be picked to find a list of points, which will help graphing the radical.

Set the radicand in $\sqrt{x}$ greater than or equal to $0$ to find where the expression is defined.

$x \geq 0$

The domain is all values of $x$ that make the expression defined.

Interval Notation:

$[0, \infty)$

Set-Builder Notation:

${x | x \geq 0}$

Interval Notation:

$[0, \infty)$

Set-Builder Notation:

${x | x \geq 0}$

Step 2

To find the radical expression end point, substitute the $x$ value $0$ , which is the least value in the domain, into $f (x) = \frac{\sqrt{x}}{6}$ .

Replace the variable $x$ with $0$ in the expression.

$f (0) = \frac{\sqrt{0}}{6}$

Simplify the result.

Simplify the numerator.

Rewrite $0$ as $0^{2}$ .

$f (0) = \frac{\sqrt{0^{2}}}{6}$

Pull terms out from under the radical, assuming positive real numbers.

$f (0) = \frac{0}{6}$

Divide $0$ by $6$ .

$f (0) = 0$

The final answer is $0$ .

$0$

Step 3

The radical expression end point is $(0, 0)$ .

$(0, 0)$

Step 4

Select a few $x$ values from the domain. It would be more useful to select the values so that they are next to the $x$ value of the radical expression end point.

Substitute the $x$ value $1$ into $f (x) = \frac{\sqrt{x}}{6}$ . In this case, the point is $(1, \frac{1}{6})$ .

Replace the variable $x$ with $1$ in the expression.

$f (1) = \frac{\sqrt{1}}{6}$

Simplify the result.

Any root of $1$ is $1$ .

$f (1) = \frac{1}{6}$

The final answer is $\frac{1}{6}$ .

$y = \frac{1}{6}$

Substitute the $x$ value $2$ into $f (x) = \frac{\sqrt{x}}{6}$ . In this case, the point is $(2, \frac{\sqrt{2}}{6})$ .

Replace the variable $x$ with $2$ in the expression.

$f (2) = \frac{\sqrt{2}}{6}$

The final answer is $\frac{\sqrt{2}}{6}$ .

$y = \frac{\sqrt{2}}{6}$

The square root can be graphed using the points around the vertex $(0, 0), (1, 0.17), (2, 0.24)$

$\begin{array}{c} x & y \\ 0 & 0 \\ 1 & 0.17 \\ 2 & 0.24 \end{array}$

Step 5

Graph g(x)=1/6 square root of x
