The parabola x = y² - 9 opens: <br> a.)up <br> b.)down<br> c.) right <br> d.)left
Zolol [24]

Answer:

Right side towards positive x axis

Step-by-step explanation:

Let us see the basic rule to find the orientation of parabolas.

1.  If power if x is 2 and y is 1 , the parabola opens up or down.

2. If the power of y is 2 and that of x is 1 , the parabola opens right or left.

3. If the coefficient of x^{2} in case 1 is negative it opens downward

4. If the coefficient of y^{2}  in case 2 is negative , it opens left towards negative x axis.

Hence our equation is

x=y^2-9

here is satisfies the case 2. hence it opens right or left . Also the coefficient of  

y^{2} is positive so it opens up to the right side , that is towards positive x axis.
