The quadratic inequality represented by the graph is:

y ≤ x^2 + 4

The quadratic inequality represented by the graph with the points (0,4) (-2,0) (2,0) is:

y ≤ ax^2 + bx + c

where a is the coefficient of x^2, b is the coefficient of x, and c is the constant term.

Using the given points, we can create a system of equations to find the values of a, b, and c:

4 = c (when x = 0)

0 = 4a - 2b + c (when x = -2)

0 = 4a + 2b + c (when x = 2)

Solving the system of equations, we get:

c = 4

a = 1

b = 0

So, the quadratic inequality represented by the graph is:

y ≤ x^2 + 4
