Answer:

9. y=5
x^(2)

10. y=2/3
x^(2)

11. y=1/10
x^(2)

12. y=-1/4
x^(2)

Explanation:

9. Use vertex form (y=a(x-h)^2+k) and insert the vertex (0,0) as (h, k).

y=a(x-0)^2 +0

Substitute the x and y values for the given point on the graph, (-1, 5)

5=a(-1-0)^2+0

Solve for a.

5=a(-1)^2

5=a

Substitute a in vertex form and solve for general form (ax^2 +bx+c)

y=5
x^(2)

Use this method to find the rest of the equations.
