# How do you graph y=-0.5 sqrt x ?

Aug 11, 2017

Compare it to the parent function and adjust accordingly to the values that are absent/differs.

#### Explanation:

Let's compare this function to the parent function: $f \left(x\right) = \sqrt{x}$

It looks like this:

graph{sqrtx [-10, 10, -5, 5]}

With your function, the only difference is the $a$-value. The $a$-value affects the vertical sense of the function.

With an $a$-value of ~0.5, the function will become vertically compressed and inverted along the $x$-axis.

Thus, it will look like this:

graph{-0.5sqrtx [-10, 10, -5, 5]}

Hope this helps :)
