Inequality_________
Set notation _______
Interval notation______

2- write the range of the function as an inequality. Using set notation and interval notation

Inequality _______
Set notation _______
Interval notation ________

Describe the end behavior of the function ( as x gets bigger and smaller, what happen to y)

____________
____________

Answer 1

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

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]
