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: 43.47
Step-by-step explanation:
This is equivalent to
f(g(x)) = x^2 + 1 That means wherever you see an x on the right, you put in g(x)
f(g(x)) = g(x)^2 + 1
f(g(x)) = (x - 4)^2 + 1 Now you can put in the 10
f(g(x)) = (10 - 4)^2 + 1
f(g(x)) = 36 + 1
f(g(x)) = 37
The point-slope intercept is y - 8 = -(x + 3). I think.
Answer:1) 1/2
2)1/3
