domain is {2.4, 4.8, 6.3, 8.8, 10.1 }
For domain, equate f(x) to each value in the range and solve for x
7x - 2.7 = 14.1 ⇒ x = = 2.4
7x - 2.7 = 30.9 ⇒ x = = 4.8
7x - 2.7 = 41.4 ⇒ x = = 6.3
7x - 2.7 = 58.9 ⇒ x = = 8.8
7x - 2.7 = 68 ⇒ x = = 10.1
Given:
The table of values is
Number of Students : 7 14 21 28
Number of Textbooks : 35 70 105 140
To find:
The rate of change and showing that the ratios of the two quantities are proportional and equivalent to the unit rate.
Solution:
The ratio of number of textbooks to number of students are
All the ratios of the two quantities are proportional and equivalent to the unit rate.
Let y be the number of textbooks and x be the number of students, then
Here, k=5.
Hence the rate of change is constant that is 5.
