Which direction does the parabola open

Answer:
left or right?
Step-by-step explanation:
if the x is squared, the parabola is vertical (opens up or down)
if the y is squared, it is horizontal (opens left or right)
if it is positive, the parabola opens up or to the right, if negative opens down or to the left
By studying the leading coefficient, we conclude that the parabola opens to the right.
To know this, we need to look at the leading coefficient. If the coefficient is positive, the parabola opens to the positive side (right). If it is negative, the parabola opens to the negative side (left).
The parabola is:
x = 9*(y - 10)^2 + 3
Rewriting it we get:
x = 9*y^2 -180y + 903
The leading coefficient is 9, which is positive, so we conclude that the parabola opens to the right.
