If you're just starting calculus, perhaps you're asking about using the definition of the derivative to differentiate 
.
We have
Expand the numerator using the binomial theorem, then simplify and compute the limit.
In general, the derivative of a power function 
is 
. (This is the aptly-named "power rule" for differentiation.)
Answer:
7. A
8. C
9. C
10. A
Step-by-step explanation:
You just have to work each one out. This is very simple.
23 = (2a) + 6
23- 6 = 2a
17 = 2a
17/2 = 2a/2
a = 8.5
hope this helps
Answer:
It is not a linear function.
Step-by-step explanation:
If in two minutes 125 people enter the park, then in 1 minute 75 people enter the park. For it ti be linear, in 3 minutes 225 would have to had entered the park, and in 4 minutes 300, 5 minutes 375.
