Look at the y axis. You can see that the graph reaches a minimum at y=3, and then grows indefinitely.
This implies that the range is . In fact, the range is exactly the set of all values reached by the function's outputs.
The vertical line test states that a graph is a function if and only if every possible vertical line crosses the graph at most once.
You can see that this is the case, so this is the graph of a function indeed.

Answer:
705
Step-by-step explanation:
141 words in 2 minutes means 70.5 words in a minute
70.5 × 10 = 705 words in 10 minutes
The answer is 9.06x10^12 or 9,060,000,000,000
Answer: D. A single number calculated from the sample that estimates a target population parameter is called a point estimator.
An interval estimator is a range of numbers that contain the target parameter with a high degree of confidence.
Step-by-step explanation:
When we evaluate an range of values for an unknown population parameter, then it is known as interval estimation .
A single number evaluated from the SAMPLE that estimates an unknown population parameter is known as a point estimator.
The general difference between point and interval estimator is the point estimator is a single value of target parameter while interval estimator is a range of numbers to estimate the values about the unknown population.
