(a)
To graph: The data table for the Keiko’s blog is to be constructed and ordered pairs from the table are to be sketch on a graph.
(a)
Explanation of Solution
The function that models the number of subscribers to Keiko’s blog is,
Where,
- K represents the number of subscribers.
- m represents the number of months.
The table is constructed as follows:
m (number of months) | K = m2+10 | (m,K) |
0 | K = 02+10 = 10 | (0, 10) |
1 | K = 12+10 = 11 | (1, 11) |
2 | K = 22+10 = 14 | (2, 14) |
3 | K = 32+10 = 19 | (3, 19) |
4 | K = 42+10 = 26 | (4, 26) |
The ordered pairs are:
The ordered pairs are plotted on the graph as follows:
(b)
To graph: The ordered pairs for the Jayden’s blog are to be sketch on a graph.
(b)
Explanation of Solution
The data table foe the Jayden’s blog is,
From the data table, the ordered pairs are represented as follows:
m (number of months) | K (number of subscribers) | m, (ordered pair) |
0 | 48 | (0, 48) |
1 | 56 | (1, 56) |
2 | 64 | (2, 64) |
3 | 72 | (3, 72) |
4 | 80 | (4, 80) |
The ordered pairs are:
The ordered pairs are plotted on the graph as follows:
