gift cards are sold by an online store to purchase movies. a graph representing this situation is shown. this step - function is discontinuous at all integers greater than 0 multiples of 5 greater than 0 multiples of 8 greater than 0
Answer
Answer:
multiples of 10 greater than 0
Explanation:
Step1: Observe the graph
The function changes values at x = 10, 20, 30, 40 etc.
Step2: Identify the pattern
These x - values are multiples of 10 greater than 0. At these points, there are jumps in the step - function, indicating discontinuity.
