Question

For 1-3, use the graph of the quadratic function.

Answer 1

Answer:

Step-by-step explanation:

From the picture attached,

Function given is a parabola, therefore, function is a quadratic function.

Domain of the function : x-values(input values) on the graph

                                      : -∞ ≤ x < ∞

Domain in set notation : {x | x ∈ All real numbers}

Domain in the form interval notation : (-∞, ∞)

End behavior of the function : As both the ends of the function are downwards towards the infinity,

                                                : As x → ∞, y → -∞ [Right end]

                                                : As x → -∞, y → -∞ [Left end]
