Answer:
Step-by-step explanation:
We have to find the domain and range of each function.
a.
It is a linear function because the degree of function is 1.Linear function is defined for all real values of x.
Therefore, the domain of given function=R
When we substitute real values in the given function then we get again real values.
Therefore, range of f=R
b.
It is a linear function .
Domain=R
Range=R
c.
C(x)=Number of calories in a sandwich containing x grams of fat.
x=Mass of fat
Mass is always a natural number.
Domain of C=N
Substitute x=1
C(1)=9(1)+130=139
C(2)=9(2)+130=18+130=148
Range of C={139,148,157,...}
d.
B(x)=Number of bacteria
x=Time in hours
Number of bacteria is a natural number and time is always a whole number.
Domain=W
Substitute x=0
Range of B={100,200,200,800,...}
Answer:
C) 8 ft
Step-by-step explanation:
you use the pythagorean theorem to find the height.
a² + b² = c²
a = radius
b = height
c = slant height
15² + h² = 17²
h = 8
Answer:
False
Step-by-step explanation:
if x=4 the answer would not be -9
x+51 would add up to 55
so it would be : 4+51=55
now if we wanted the answer to be -9 , x would have to be different
-60+51=-9
but in this case x is no -60, it's 4, so no this statement is false.
Answer:
are you sure there isn't a 90?
Step-by-step explanation:
Because there are 4 quarters in a whole, so 22 x 4 = 88, and there are 2 quarters in 1/2 so it would be 88+2, which is 90.
Answer:
D. (-2,-5), (0, -7), (1, -4)
Step-by-step explanation:
From Function Theory we must remember that range of a function is the set of images related to elements of the domain. In this case, we must find the image of each of the three elements that forms the domain of , which are: , and .
Then we proceed to find all elements of range:
Which corresponds to option D.
