Seven year old students at a elementary school were given 10 yard
1 answer:
Answer:
The correct option is a. 10 ≤ x ≤ 60, or x is from 10 to 60.
Step-by-step explanation:
Note: This question is not complete. The complete question is therefore provided before answering the question as follows:
Seven-year-old students at an elementary school were given a 10-yard head start in a race. The graph shows how far the average student ran in 30 seconds. A line graph with Distance, in yards, on the x axis and Age of Runner on the y axis. The x axis has a scale from 0 to 80 in increments of 10. The y axis has a scale of 0 to 8 in increments of 2. A straight line connecting 10, 7 and 60, 7 is drawn. Which statement best describes the domain of the function represented in the graph?
a. 10 ≤ x ≤ 60, or x is from 10 to 60
b. 7 ≤ x ≤ 60, or x is from 7 to 60
c. 7 ≤ x ≤ 10, or x is from 7 to 10
d. 0 ≤ x ≤ 10, or x is from 0 to 10
Note: See the attached photo for the graph referred to in the question.
The explanation of the answer is now given as follows:
In statistics, the domain of a function refers to the values in the x-axis where there is a corresponding value in the y-axis.
In this question, the only defined values for x are from 10 to 60 with a corresponding constant value of 7 in the y-axis.
Based on this, the correct statement that best describes the domain of the function represented in the graph is therefore option a. 10 ≤ x ≤ 60, or x is from 10 to 60.
