Which is the rate of change for the interval between 3 and 6 on the x-axis?
–3
–2
2
3

Answer:
The correct answer is 2.
Step-by-step explanation:
To find this, first identify the ordered pairs at those two points. They would be (3, -2) and (6, 4). Then use the slope formula with those two points to find the rate of change.
m(slope) = (y2 - y1)/(x2 - x1)
m = (4 - - 2)/(6 - 3)
m = 6/3
m = 2
Answer:
2
Step-by-step explanation:
Rate of change on the given interval a to b is
[tex]\frac{f(b)-f(a)}{b-a}[/tex]
a=3 and b=6
f(a) and f(b) are the y values on the graph at x=3 and x=6
f(3)= -3 and f(6) is 4
Now plug in the values in the formula
[tex]rate of change =\frac{4-(-2)}{6-3} =\frac{6}{3} =2[/tex]
answer is 2
