To find: The equation for the parabola.
Given information:
To write an equation for the parabola.
Concept used:
Parabolas that open to the right or left are inverse relations of upward-or downward opening parabolas. The standard equation for the parabolas that open to the right or left is:
Explanation:
From the graph of the right opening parabola, it follows that:
The vertex
