Remember, x^-1=1/x
so
f(-1)=4(7)^-1=4(1/7)=4/7
f(2)=4(7)^2=4(49)=196
Answer:
The relation is a FUNCTION
Step-by-step explanation:
as you can see the value of domain or the x there's no repeating number at all.
First, pull out a factor of
.
Notice that when
(which you can arrive at via the rational root theorem), you have
which means you can pull out a factor of
. Upon dividing you get
The rational root theorem will come in handy again, suggesting that
appears a second time as a root, which means
Now this is more readily factored without having to resort to the rational root theorem. You have
so in fact,
shows up as a root for a third time.
So, you have
Two roots are obvious,
and
(with multiplicity 3). The remaining two are given by
Answer:
1.86 (rounded to nearest hundredth) inches of snow in 1 hour
Step-by-step explanation:
Divide 13 inches of snow by 7 hours
The answer is 1.8571428571428571428571428571429
Round to the nearest hundredth
1.86
Hope this helped :)
It is continuous because the function can be further simplified thus, cancelling the denominator.
f(x) = x(x+5)(x+2) / (x+5)
f(x) = x(x+2)
The function is continuous everywhere/ in any domain.
