Question

If the parent function is √x, describe the translation of the function.√x-1

One unit down from √x


One unit up from √x


One unit to the right of √x


One unit to the left of √x

Answer 1

The translation is one unit down from
`y = √(x)`

Explanation:

The parent function is
`y = √(x)` ............ (1)

And the translated function is
`y = √(x) - 1` ............ (2)

Now, we have to describe the translation.

The value of y in the equation (2) is one less than that value in equation (1).

Therefore, the translation is vertical {Since, the y-value changes} and it is by one unit down.

Hence, the translation is one unit down from
`y = √(x)`. (Answer)
