Answer:
Domain: (-∞, ∞)
Range: (-∞, ∞)
General Formulas and Concepts:
Algebra I
- Reading a Cartesian plane
- Domain is the set of x-values that can be inputted into function f(x)
- Range is the set of y-values that are outputted by function f(x)
- Interval Notation - [Brackets] denote inclusion, (parenthesis) denote exclusion
Explanation:
According to the graph, we see our x-values span from negative infinity to positive infinity:
Interval Notation - (-∞, ∞)
Inequality Notation - ∞ < x < ∞
According to the graph, we see our x-values span from negative infinity to positive infinity:
Interval Notation - (-∞, ∞) or all real numbers
Inequality Notation - -∞ < y < ∞
