The equations are
To find:
Which function is changing more quickly.
Solution:
The slope intercept form of a line is
Where m is slope and b is y-intercept.
On comparing with the slope intercept form, we get
On comparing with the slope intercept form, we get
Since, , it means the absolute rate of change of second function is greater than the first function.
Therefore, the second function is changing more quickly.
