Answer:
9. B 10. C 11. A 12. C
Explanation:
Greater rate of change simply means slope! Which ever of the functions has the greatest slope (positive or negative)
9.
a. The graph shows the line going up by 4, and across by 3, or, a slope of 4/3
b. the table is increasing by 10, so, 10/1
c. -6 = -6/1, out of all of these, we divide by the denominators and determine which number is the greatest, ignoring whether or not the value is positive or negative
a. 4/3 = 1.333333
b. 10/1 = 10
c. -6/1 = -6 (remember, ignore the sign)
In this case, B is the greatest number, therefore, it has the greatest rate of change
10.
a. -3 / 3 = -1 (ignore the negative!)
b. 2/1 = 2
c. 4/1 = 4
In this case, C, is the greatest number, meaning its rate of change is highest
11.
a. -1/3 = -0.333333 (ignore the yk what!)
b. 0.25/1 = 0.25
c. -1/5 = -0.20 (you already know)
In this case, a, is the greatest number, meaning, its rate of change is the highest
12.
a. 0/1 = 0
b. 0.5/1 = 0.5
c. 2/1 = 2
In this case, c, is the greatest number, meaning, its rate of change is the highest.
Hope this helps!! <3
