Answer:
Step-by-step explanation:
0 is not an interval, it is just the origin
hard to make an estimate without knowing the limits.
average rate of change will be Δy / Δx or (y - y₀) / (x - x₀)
as (0, 0) is the origin and appears to be on the plot line, the average rate of change will be y/x for any other point on the curve relative to the origin.
EDIT
for interval 0 ≤ x ≤ 8
at x = 8 y appears to be -24
average change is -24 / 8 = -3

Answer:
a) 490
b) 240
Step-by-step explanation:
b) It is convenient to answer part B first.
The number owning only a fax will be the number owning a fax less the number that own both a fax and a copier:
420 -180 = 240 . . . . number owning only a fax
__
a) The number owning one or the other will be the number owing a copier (which includes those owning both) plus the number owning only a fax:
250 +240 = 490 . . . . number owning either
_____
If you want to work part A first, then you need to use the relation ...
n(A∪B) = n(A) +n(B) -n(A∩B)
Basically, powering something is multiplying something by itself.
so, 2 to the power of 10 is 1024
why? because
2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 = 1024
(see? I multiplied 2 10 times!)
