Question

《RANGE OF QUADRATIC FUNCTION》 ¿¿¿¿¿
​

Answer 1

$\huge\mathfrak{\underline{explanation}}$

The graph of any quadratic function, of the form f(x) = a x 2 + b x + c, which can be written in vertex form as follows f(x) = a(x - h) 2 + k , where h = - b / 2a and k = f(h) is either a parabola opening up, when a > 0, or a parabola opening down, when a < 0 (see graphs of several quadratic function below).

Answer 2

HEY MATE HERE IS YOUR ANSWER

The values of a, b, and c determine the shape and position of the parabola. The domain of a function is the set of all real values of x that will give real values for y. The range of a function is the set of all real values of y that you can get by plugging real numbers into x. The quadratic parent function is y = x2.
