Given the graphed function below, which of the following ordered pairs are found on the inverse function?
O A. (11, 2), (4,1). (3,0), (2, -1),(-5, -2)
O B. (-11, -2).(-4-1),(-3,0),(-2, 1),(5,2)
O C. (2, 11), (1,4), (0, 3).(-1,2), (-2,-5)
O D. (-2, 11).(-1,4),(0,3), (1, 2), (2,-5)

Yes it is a quadratic function. A quadratic function contains the term x^2 and x^2 has the highest exponent in the whole function of a quadratic function. What I mean by this is for example x^3 + x^2 + 2x + 3 is not a quadratic. It includes x^2 but x^3 has the largest exponent. That makes that equation a cubic. Just for more info the largest exponent is referred to as the degree of the function so the degree of a quadratic function is always 2. Hope this helps!
