The range of a quadratic function is the set of all real numbers less than or equal to 3. Which equations could represent the function?

Select TWO correct answers.
f(x) = (x - 2)^2 + 3
f(x) = -(x - 2)^2 + 3
f(x) = -x^2 + 3
f(x) = (x + 3)^2 + 2
f(x) = -(x +3)^2 + 2

f(x) = -(x - 2)^2 + 3

f(x) = -x^2 + 3
