The Function F(X) = −(X + 5)(X + 1) Is Shown. On A Coordinate Plane, A Parabola Opens Down. It Goes Through (Negative 5, 0), Has A Vertex At (Negative 3, 4), And Goes Through (Negative 1, 0). What Is The Range Of The Function? All Real Numbers Less Than Or Equal To 4 All Real Numbers Less Than Or Equal To −3 All Real Numbers Greater Than Or Equal To 4 All Real Numbers Greater Than Or Equal To −3. C) all real numbers greater than or equal to 4: The domain of a function is defined as the set of all input values for the function f (x), whereas the range of a function is the set of all possible output values.
The function f (x) = (x − 4) (x − 2) is shown. Explore math with our beautiful, free online graphing calculator. See the graph, the definition of parabola, and the expert.
