(43+45+47+49)=184
They are all odd and they are in consecutive order (one after another)
$15,822 is the correct answer, you multiply 36 by $419 and add the down payment of $738
Answer:
f
(
x
)
=
2
, means, whatever be the value of

, f(x)=2#.
∴
f
(
−
4
)
=
2
.
Answer: we should have that:

Step-by-step explanation:
We know that f(x) is an odd function, this means that f(-x) = -f(x)
We know that:

this means that wen we aproximate to zero for the right (the positive side) we have that the value is.
First, this tell us that f(x) can not be a continue function, because of the fact that is odd we will have that when we aproximate the same lim but from the negative side, we will have that:

Answer:
968 km/h
