In order to be a function all the x’s must be different. Number 5 is a function. Number 6 is not a function
Answer: C, You can tell the trend line is incorrect since all of the points are below it. A trend line should be in-between all of the points to give the best estimate.
Step-by-step explanation:
Given:
Big figure = 20 ft
Small figure = 7 ft
Take note: In finding the scale factor, we must make sure that the measurements of both figures are the same sides or line.
20 feet / 7 feet = 2.86 scale factor.
This means that the big figure is 2.86 times bigger than the small figure.
If the arrow had been pointed from the small figure to the big figure.
7 feet / 20 feet = 0.35 scale factor.
This means that the small figure is only 0.35 of the big figure.
Both are scale factors but in different perspectives.
