Answer:

A.

Step-by-step explanation:

We are given graph in the figure.

We have to find a quadratic graph

Quadratic function: It is that function in which degree of polynomial is 2.

Quadratic function is given by


ax^2+bx+c

Quadratic graph: it is defined as that graph which is like as parabola along y- axis , along x- axis, along negative x- axis and along negative y- axis.

In option A: The given graph is parabola along y- axis.Therefore, it is quadratic graph.

Hence, option A is true.

In option B: the graph is not the graph of parabola.So,given graph is not quadratic graph.

Hence, option B is true.

In option C:It is graph of line .The equation of line
y=mx+c

It is not a quadratic equation .Hence, the graph is not quadratic graph.

Therefore, option C is false.

In option D: The given graph is not like as parabola along any axis.

Therefore, it is not a quadratic graph.

Hence, option D is true.
