Given is a graph of a parabola.
We have to find the equation of the paabola.
We observe from the graph the following points.
i) Vertex is (0,0)
ii) Open downward
iii) Axis of symmetry is y axis or x=0
iv) It passes through (1,4)
The parabola will be of the form
Substitute x=1 and y =4, to find a
1 = -4a(4)
a =
Hence equation would be
