Question

The parabola opens: y=√x-4 (principal square root) up down right left

Answer 1

right towards positive x axis

Explanation:

In order to find the orientation of the parabolas we can follow following steps.

1. if in the equation x is squared , the parabola opens up. Also if its coefficient is negative it opens down.

2. If y is squared , the parabola opens right , and its coefficient is negative , it opens left

but before that we have to convert our function in standard form of the parabola. Our equation is

`y=√(x-4)`

hence we square on both sides

`y^2=x-4`

which is now into one of the standard form of a parabola. here y is squared and its coefficient is not negative hence it opens towards right.
