gift cards are sold by an online store to purchase movies. a graph representing this situation is shown. this step - function is discontinuous at multiples of 8 greater than 0. complete a gift card in the amount of $25 will purchase 3 movies. complete the domain of the function is all natural numbers ≥ 0 real numbers ≥ 0 integers ≥ 0 done
Answer
Explanation:
Step1: Analyze domain concept
The domain represents the possible values of the independent - variable. In the context of the amount on a gift - card, it can take on any non - negative real number value (e.g., $25.50 could potentially be a gift - card amount in a more general scenario where partial amounts are possible).
Step2: Evaluate options
Natural numbers are positive whole numbers starting from 1 ($1, 2, 3,\cdots$). Integers include negative whole numbers, zero, and positive whole numbers ($\cdots,- 2,-1,0,1,2,\cdots$). Real numbers include all rational and irrational numbers and can be non - negative. Since the amount on a gift card can be any non - negative real number (like $0, 0.5,1,1.5,\cdots$), the domain is all real numbers $\geq0$.
Answer:
real numbers $\geq0$
